Autodesk Inventor 2026 on Linux

Status: WORKING — Full UI, Part/Assembly/Drawing creation, materials, CPU ray tracing.

Autodesk Inventor 2026 Professional running under Wine 11.4 on Linux. WineHQ rates every version of Inventor as "Garbage". This project demonstrates it can be done, documents every fix in enough detail to reproduce, and provides scripts to rebuild the environment from scratch in ~15 minutes.

This is believed to be the first instance of Inventor running on Linux.

Requirements

Hardware:

x86_64 CPU
GPU with Vulkan/D3D11 support (tested: NVIDIA RTX 4080 + Intel Arc Meteor Lake)

Software:

Linux, kernel 6.x+ (tested: CachyOS / Arch)
Wine 11.4 (vanilla — not Proton)
DXVK 2.7.1
winetricks
ImageMagick (convert) — for icon extraction
A working Autodesk Inventor 2026 Professional installation on Windows, accessible at /mnt/windows/

Disk space:

~20 GB — Wine prefix + Inventor binaries
~7 GB — Content Center (optional)

Account:

Valid Autodesk account with Inventor 2026 subscription (SSO required on first launch; subsequent launches use cached token)

Quick Start

# Install system prerequisites (CachyOS/Arch)
sudo bash scripts/phase0-setup.sh

# Export Autodesk registry keys from your Windows installation
bash scripts/export-registry.sh

# Build the Wine prefix (~15 min; requires Windows partition mounted at /mnt/windows)
bash scripts/rebuild-prefix.sh

# Apply the system-wide Wine wbemprox patch (required for CPU ray tracing)
# See: Setup Guide → Wine wbemprox Patch

# Register the OAuth2 protocol handler (required for first-time login)
# See: Setup Guide → OAuth2 Protocol Handler

# Launch
bash scripts/launch-inventor.sh

On first launch Inventor opens a Firefox window for Autodesk SSO login. After login the license is cached and subsequent launches skip the browser entirely.

Architecture

Inventor requires three Windows services running in order inside the Wine prefix:

Wine prefix: ~/.wine-inventor2026

Drive mappings:

Drive	Path
`C:`	`~/.wine-inventor2026/drive_c`
`D:`	`/mnt/Storage` (user data)
`Z:`	`/` (Linux root)

Setup Guide

1. Build the Wine Prefix

scripts/rebuild-prefix.sh copies the Inventor installation from /mnt/windows/ into a fresh Wine prefix and applies all known fixes. This is the authoritative setup procedure.

What it does (28 steps):

Wipes and recreates the Wine prefix
Sets Windows 10 compatibility mode
Installs DXVK (D3D9/D3D11 → Vulkan translation)
Copies Inventor binaries, ASC SharedComponents, MSVC/MFC runtimes, RealDWG
Installs WebView2 runtime, Identity Manager, Licensing Service, .NET 8
Imports registry keys: Inventor, SharedComponents, licensing, protocol handler
Installs IDSDK SSO plugin into the Licensing Agent (IDSDKVersionCompatibility.config)
Disables non-essential and Wine-broken addins (see notes/disabled-addins.md)
Moves InteractiveTutorial.dll — triggers wine-mono fatal assertion if left in place
Disables CER crash reporter (senddmp.exe) — causes false-positive process termination
Removes bcp47langs.dll stubs — Proton placeholder causes NULL crash in all Autodesk apps
Copies Design Data, Templates, Textures
Applies OGSFactory.dll binary patch (§OGSFactory.dll Binary Patch)

bash scripts/rebuild-prefix.sh

Requires /mnt/windows/ to be mounted with the source Windows installation.

2. Wine wbemprox Patch

Wine's WMI implementation (wbemprox.dll) is missing Win32_TimeZone. OGSFactory.dll queries this class during 3D viewport initialisation; without it, the rendering pipeline initialises in a degraded state and CPU ray tracing produces flat results.

This patch modifies the system-wide Wine installation and must be reapplied after any Wine upgrade.

Build and install:

cd /tmp
curl -LO https://dl.winehq.org/wine/source/11.x/wine-11.4.tar.xz
tar xf wine-11.4.tar.xz && cd wine-11.4

patch -p1 < ~/Projects/Inventor\ on\ linux/patches/wbemprox-timezone.patch

./configure --enable-win64 --without-x --without-freetype
make -C dlls/wbemprox

sudo cp dlls/wbemprox/x86_64-windows/wbemprox.dll \
    /usr/lib/wine/x86_64-windows/wbemprox.dll

Verify:

wine cscript //NoLogo Z:\\tmp\\test_tz.vbs
# Expected output: Win32_TimeZone: found 1 items

Win32_TimeZone is a standard WMI class used by many applications. This patch is a strong candidate for upstreaming to Wine.

3. OAuth2 Protocol Handler

The adskidmgr:// URI scheme passes the OAuth2 authorization code from Firefox back to the running Identity Manager server. Register the Linux handler:

# Create the .desktop handler
cat > ~/.local/share/applications/adskidmgr-handler.desktop << EOF
[Desktop Entry]
Type=Application
Name=Autodesk Identity Manager
Exec=$HOME/.local/bin/adskidmgr-callback %u
MimeType=x-scheme-handler/adskidmgr;
NoDisplay=true
EOF

# Symlink the callback script
ln -sf ~/Projects/Inventor\ on\ linux/scripts/adskidmgr-callback.sh \
    ~/.local/bin/adskidmgr-callback

# Register
xdg-mime default adskidmgr-handler.desktop x-scheme-handler/adskidmgr
update-desktop-database ~/.local/share/applications

The callback script (scripts/adskidmgr-callback.sh) creates the AdOAuth2Code IPC file then launches a client Identity Manager instance to deliver the auth code. It must not kill wineserver — that would destroy the running Inventor session.

4. Desktop Entry (optional)

# Extract icon from Inventor binary
convert \
    ~/.wine-inventor2026/drive_c/Program\ Files/Autodesk/Inventor\ 2026/Bin/idv.ico \
    -thumbnail 256x256 -flatten \
    ~/.local/share/icons/hicolor/256x256/apps/autodesk-inventor-2026.png

# Symlink for a spaces-free executable path
ln -sf ~/Projects/Inventor\ on\ linux/scripts/launch-inventor.sh \
    ~/.local/bin/launch-inventor

# Create the .desktop entry
cat > ~/.local/share/applications/autodesk-inventor-2026.desktop << 'EOF'
[Desktop Entry]
Type=Application
Name=Autodesk Inventor 2026
Exec=launch-inventor
Icon=autodesk-inventor-2026
Categories=Engineering;Graphics;
EOF

update-desktop-database ~/.local/share/applications

5. Drive Mappings

# Map your data drive (adjust path as needed)
ln -sf /mnt/Storage ~/.wine-inventor2026/dosdevices/d:

6. Content Center

Required for standard hardware components (bolts, bearings, etc.) in assemblies. 7.1 GB.

cp -r "/mnt/windows/ProgramData/Autodesk/Inventor 2026/Content Center" \
    "$HOME/.wine-inventor2026/drive_c/ProgramData/Autodesk/Inventor 2026/"

Technical Details

OGSFactory.dll Binary Patch

Root Cause

OGSFactory.dll queries WMI during 3D viewport creation. The function at RVA 0x57968:

Calls IWbemServices::CreateInstanceEnum() (vtable slot 18) for Win32_TimeZone
Calls IEnumWbemClassObject::Next(2000, 1, &ppObject, &uReturned) (vtable slot 4)
Uses the returned object to set up the Protein material/lighting pipeline

Under Wine, Next() returns S_OK but leaves ppObject = NULL. The function then unconditionally dereferences [ppObject], causing access violation 0xC0000005.

The crash occurs inside a Win32 window message callback. Wine's user_callback_handler logs "ignoring exception c0000005" and continues with corrupted state. On Windows, legacyCorruptedStateExceptionsPolicy would catch this. Under Wine it is fatal.

The Fix

Two code-cave patches redirect the crash sites to null-check trampolines written into .text section padding:

Patch 1 — file offset 0x56E5B (RVA 0x57A5B):

; Original (crashes when rcx = NULL):
;   mov  rcx, [rsp+0x70]
;   mov  rdx, [rcx]         ← access violation
;
; Replaced with: jmp to code cave at 0x110A60
e9 00 9c 0b 00   ; jmp  +0xB9C00
90 90 90         ; nop  nop nop  (alignment padding)

; Code cave at file offset 0x110A60:
48 8b 4c 24 70   ; mov  rcx, [rsp+0x70]
48 85 c9         ; test rcx, rcx
0f 84 11 64 f4 ff; je   0x57A7F          ; skip to cleanup if NULL
48 8b 11         ; mov  rdx, [rcx]       ; safe dereference
e9 ed 63 f4 ff   ; jmp  0x57A63         ; return to normal flow

Patch 2 — file offset 0x56EA8 (RVA 0x57AA8): same pattern, second dereference of the same pointer. Code cave at 0x110A76.

Apply (already integrated into rebuild-prefix.sh step 27):

DLLPATH="$HOME/.wine-inventor2026/drive_c/Program Files/Autodesk/Inventor 2026/Bin/OGSFactory.dll"
cp "$DLLPATH" "${DLLPATH}.original"

# Patch 1: redirect crash site
printf '\xe9\x00\x9c\x0b\x00\x90\x90\x90' \
    | dd of="$DLLPATH" bs=1 seek=$((0x56E5B)) conv=notrunc 2>/dev/null
# Patch 1: null-check trampoline
printf '\x48\x8b\x4c\x24\x70\x48\x85\xc9\x0f\x84\x11\x64\xf4\xff\x48\x8b\x11\xe9\xed\x63\xf4\xff' \
    | dd of="$DLLPATH" bs=1 seek=$((0x110A60)) conv=notrunc 2>/dev/null

# Patch 2: redirect crash site
printf '\xe9\xc9\x9b\x0b\x00\x90\x90\x90' \
    | dd of="$DLLPATH" bs=1 seek=$((0x56EA8)) conv=notrunc 2>/dev/null
# Patch 2: null-check trampoline
printf '\x48\x8b\x4c\x24\x70\x48\x85\xc9\x0f\x84\x48\x64\xf4\xff\x48\x8b\x11\xe9\x24\x64\xf4\xff' \
    | dd of="$DLLPATH" bs=1 seek=$((0x110A76)) conv=notrunc 2>/dev/null

Side Effects

The trampolines skip the Protein material/lighting pipeline initialisation:

Materials render slightly darker than on Windows
Realistic Visual Style reports "Material Library not available"
GPU ray tracing capability detection may be affected

Fixing these requires identifying and implementing the Wine interface that currently returns NULL. See §Open Problems.

Wine wbemprox / Win32_TimeZone

patches/wbemprox-timezone.patch adds a complete Win32_TimeZone implementation to Wine's dlls/wbemprox/builtin.c:

Addition	Description
`col_timezone[]`	21-property column definition matching the MSDN `Win32_TimeZone` schema
`struct record_timezone`	Record layout matching the column definition
`fill_timezone()`	Calls `GetTimeZoneInformation()` and populates all fields
Table entry	Registered in `cimv2_builtin_classes[]` alphabetically before `Win32_VideoController`

See patches/wbemprox-timezone.patch for the complete diff.

Key Discoveries

Non-obvious facts found during the porting work. Read these before investigating any open issue.

1. WPF GAC removal is mandatory. Wine-mono ships stub WPF DLLs in the GAC (PresentationCore, PresentationFramework, WindowsBase, System.Xaml). When Inventor loads, mono hits a fatal assertion in the stub and calls System.Environment.Exit(). Deleting only the DLL files (not the directories) is the fix. wineboot -u recreates directories but not files, so the fix persists.

2. bcp47langs.dll Proton stub causes a NULL crash. Proton ships a stub bcp47langs.dll that returns NULL from all calls. This crashes all Autodesk apps. Remove the file or disable the DLL override entirely.

3. Identity Manager uses Boost.Interprocess for IPC. The IDSDK IPC directory ($WINEPREFIX/drive_c/ProgramData/Autodesk/IDSDK/<USERNAME_HEX>/interprocess/01000000/) must be wiped before each launch. Stale lock files cause Identity Manager to deadlock indefinitely. The directory name is the ASCII username encoded as uppercase hex (e.g. alice → 616C696365); the launch script computes this dynamically.

4. OAuth2 callback: launch a client, never kill wineserver. The adskidmgr:// handler must spawn a new Identity Manager client instance (which passes the auth code and exits). Killing wineserver destroys the running Inventor session.

5. CER crash reporter terminates the process. Autodesk's senddmp.exe intercepts native crashes, shows a report dialog, then exits the process. Disabling it by renaming allows Inventor to survive recoverable crashes.

6. .NET 8 CoreCLR runs under Wine 11.4. Load chain: ClrAddinLoader.dll → hostfxr.dll → hostpolicy.dll → coreclr.dll. Use WINEDLLOVERRIDES="msquic=" to suppress MSQUIC networking crashes.

7. Wine's user_callback_handler swallows exceptions. A native crash inside a Win32 window message callback logs "ignoring exception c0000005" and continues. On Windows the exception propagates to the managed handler. Under Wine it is silently absorbed, leaving corrupted state that eventually terminates the process.

8. DXVK always reports AMD Radeon RX 6700 XT. Regardless of actual GPU hardware. May affect OGS GPU capability detection but has no functional impact on D3D11 rendering.

9. IDSDK SSO plugin must be manually placed in the Licensing Agent. The IDSDKVersionCompatibility.config file and SSOPlugin/Current/*.dll must exist under the Licensing Agent directory. They are not discovered from the Identity Manager installation path.

10. OGS queries three WMI classes during graphics init. Win32_TimeZone, Win32_VideoController, and Win32_BIOS are queried from OGSFactory.dll!fn@0x57968. Missing classes cause silent pipeline degradation or a crash.

Graphics Settings

Stored in user.cfg inside the Wine prefix. Do not change these unless you understand the consequences — certain combinations produce black or greyscale rendering.

UseINVBasicMaterial = 1    ; basic material system — working
UsePrismMaterial    = 0    ; PBR — causes issues when enabled alone
UseUberMaterial     = 0    ; advanced materials — causes black faces
GammaCorrect        = 0    ; gamma correction — causes inverted brightness
DMEffectType        = 0x80 ; shading mode — changing to 0 breaks face colours
OGSCon              = 2    ; D3D11 mode
UseAccel            = 1    ; hardware acceleration
UseGPURaytracing    = 1    ; GPU RT — greyed out until D3D12 works
UseRRT              = 1    ; RapidRT engine

Open Problems

Known issues with investigation leads. Each entry has enough context for a skilled developer to pick it up cold.

1. Materials Too Dark (highest priority)

Symptom: Material faces render noticeably darker than on Windows.

Root cause: The binary patch skips the portion of OGSFactory.dll!fn@0x57968 that initialises the Protein material/lighting pipeline, because the COM call at RVA 0x57A40 returns ppObject = NULL.

Investigation path:

Use OGSFactory.dll.original (pre-patch) for analysis — it crashes but reveals the real call sequence
Set a winedbg breakpoint at RVA 0x57A40 (the IEnumWbemClassObject::Next() call)
Inspect rax/rcx/rdx after the call to identify the IID and vtable slot
Search Wine source for that IID — implement it if missing, or fix the return value if stubbed incorrectly
If the interface is a sub-query on the Win32_TimeZone instance, the fix belongs in wbemprox

Fixing this will likely also fix: Realistic Visual Style ("Material Library not available")

2. iLogic (COM Interop E_FAIL)

Symptom: iLogic addin fails with E_FAIL 0x80004005 on DesignProjectManager.get_ActiveDesignProject.

Investigation path:

Re-enable the addin (move autodesk.ilogic.inventor.addin from Bin/Addins/disabled/ back to Bin/Addins/)
Run with WINEDEBUG=+ole,+rpc,err+all and capture the COM trace
The failure is on a .NET → COM boundary via ClrAddinLoader
Check whether Wine's ole32/oleaut32 correctly implements the specific IDispatch interface used by iLogic
May be a .NET 8 / wine-mono interop issue at the IDispatch marshalling layer

3. GPU Ray Tracing

Symptom: GPU ray tracing option is greyed out in Inventor's render settings.

Root cause: Requires D3D12 + DXR (DirectX Raytracing). Wine does not ship VKD3D-Proton by default.

Fix path: Install VKD3D-Proton, add d3d12 = native to DLL overrides, and test whether OGS detects the D3D12 device and enables the GPU RT path.

Risk: VKD3D-Proton and DXVK coexistence for D3D11/D3D12 needs testing.

4. Identity Manager Intermittent Deadlock

Symptom: Occasionally Identity Manager starts but never reaches "SSO Server is ready". Hangs in Boost.Interprocess lock acquisition.

Current mitigation: The launch script wipes the IPC directory before each start. This prevents the issue most of the time.

Remaining edge case: If the system is hard-killed while Identity Manager is running, stale IDSDKQuit-v2-* files from a different session path may survive and block the next start.

Fix path: Wipe all subdirectories under .../IDSDK/<USERNAME_HEX>/interprocess/ before launch, not just the single session directory.

Never Do These Things

These actions permanently break the Wine prefix or silently corrupt Inventor's state. There is no recovery path short of a full rebuild-prefix.sh run.

Action	Consequence
`winetricks dotnet48`	Removes wine-mono; all .NET loading breaks permanently
`mscoree = native` DLL override	Prevents PE loading entirely
Copy Windows .NET assemblies into wine-mono GAC	Triggers mono fatal assertion on every startup
Kill `wineserver` in OAuth callback	Destroys the running Inventor session
Place Proton `bcp47langs.dll` in system32	NULL crash in all Autodesk apps
`UseUberMaterial=1` or `GammaCorrect=1`	Black / inverted face rendering
Update Wine without rebuilding wbemprox	Loses `Win32_TimeZone`; breaks CPU ray tracing
Leave IDSDK IPC directory dirty across restarts	Identity Manager deadlock on next launch

Session History

2026-03-20 — Session 1: First successful Inventor launch. WPF GAC removal discovered as the enabling fix for .NET loading. Identity Manager SSO working via Firefox + OAuth2. Inventor ran 4+ minutes at 242 MB RSS. Identity Manager intermittent deadlock identified as a Boost.Interprocess stale lock issue.

2026-03-20 — Session 2: Identity Manager crash traced to bcp47langs.dll Proton stub. Full ribbon UI achieved. OGS crash on Part creation traced to OGSFactory.dll null pointer via module load tracing and disassembly. Binary code cave patch developed and applied. Design Data, Templates, Textures copied. Part creation working.

2026-03-21 — Session 3: Wine wbemprox patched to add Win32_TimeZone WMI class (built from Wine 11.4 source). CPU ray tracing produces real non-flat results. Shared Materials Library (535 MB), Backgrounds, Home page, Content Center (7.1 GB), and full Autodesk registry imported. Default .ipj project file configured with library search paths. Desktop entry and icon created. Drive D: mapped to /mnt/Storage. ClearType font AA enabled. Materials, assemblies, and CPU ray tracing working.
