Autodesk Complete Uninstaller
A single-file Windows batch tool that fully detects, uninstalls, and deep-cleans every Autodesk product from a machine — all versions from 2015 through 2026+. Achieves a verified zero-remnant clean on real machines without requiring a reboot.
Built because Autodesk's own Uninstall Tool was discontinued after 2020, and the standard Windows "Add/Remove Programs" method leaves behind gigabytes of orphaned files, registry keys, services, and licensing artifacts that block fresh installations and waste disk space.
Antivirus Note: The VirusTotal scan shows 0/62 Clean — no security vendor flags this file as malicious. The script is open-source and you can read every line in Notepad before running it.

- Auto-detects all installed Autodesk products by scanning both 64-bit and 32-bit Windows registry hives
- Classifies each product's installer type (ODIS for 2020+, MSI for legacy, BitRock) and routes to the correct silent uninstall method automatically
- Dependency-ordered uninstall — removes products in the correct sequence:
- Add-ins, plugins, enablers, language/content packs
- Main applications (AutoCAD, Revit, Inventor, Maya, 3ds Max, etc.)
- Material Libraries (Medium Resolution → Base Resolution → Core)
- Desktop App, Single Sign-On
- Genuine Service (always last)
- Multi-pass retry system — rescans registry after each pass, retries failed products up to 4 times
- ODIS orphan detection — identifies products whose metadata XML is missing and force-cleans their registry entries
- Deep clean removes all traces: folders, registry keys, user file associations, COM objects, Windows services, scheduled tasks, firewall rules, shortcuts, shell extensions, FLEXnet files, CLM/LGS license data, ADUT transition data, ODIS cache, environment variables
- Shell extension unregistration — unregisters
AcShellExtension.dll(DWG thumbnail handler) and restarts Explorer to release file locks - WMIC wildcard process kill — terminates ANY process running from Autodesk paths, not just hardcoded names
- Shortcut cleanup — removes desktop shortcuts, Start Menu folders, and taskbar pins
- Registry backup before deletion —
.regexport files saved to Desktop - System Restore Point creation (optional) with 24-hour limit bypass
- Comprehensive diagnostics — generates
diagnostics.log,uninstall_log.txt, andverify_details.txtfor troubleshooting - 12-point deep verification scan — checks products, processes, services, folders, user data, registry hives, COM/CLSID deep scan, legacy licensing, env variables, shortcuts, tasks, and firewall rules
- Remnant search tool — scans entire C: drive for any Autodesk folders, deep-searches registry for file associations and COM objects
- No reboot required — achieves full clean in a single run on real machines
- Single
.batfile — no dependencies, no installation, no PowerShell execution policy issues

The tool creates a folder on your Desktop: Autodesk_Uninstaller\
| File | Purpose |
|---|---|
uninstall_log.txt |
Product-level log with commands executed and exit codes |
diagnostics.log |
System info, ODIS state, phase timestamps, error output |

Registry backups (can double-click to restore) |
reboot_cleanup.bat |
Auto-scheduled cleanup for locked folders (if needed) |
- Back up custom templates, families, and profiles — AutoCAD CUI files, Revit families, plot styles, etc. will be permanently deleted
- Close all Autodesk applications before running
- Run as Administrator — right-click the
.batfile and select "Run as administrator"
The FlexNet Licensing Service 64 is shared between Autodesk and Adobe. If you use Adobe software, do NOT delete this service when prompted.
- Run [5] Final Verification to confirm clean state
- Registry backups (
.regfiles) are saved toDesktop\Autodesk_Uninstaller\ - The tool briefly restarts Windows Explorer during cleanup (taskbar disappears for ~2 seconds) — this is normal
| Problem | Solution |
|---|---|
| Script closes immediately | Right-click → Run as administrator |
| "Access denied" errors | Ensure no Autodesk apps are running; try again |
| Products remain after uninstall | Run [4] Deep Clean to force-remove |
| ODIS uninstaller fails (exit:1) | Phase C2 automatically force-cleans these |
| Folders show as LOCKED | Tool uses takeown/icacls + Explorer restart; run Deep Clean again |
| Verification shows items in [7/12] | Run [4] Deep Clean to remove file associations |
| Error 103 during install | Run [10] Fix Error 103 for 9-point ODIS diagnosis and guided repair |
| Antivirus blocks or quarantines the script | Add an exclusion for the .bat file or temporarily disable real-time protection; this is a false positive |
| Windows SmartScreen blocks the file | Click More info > Run anyway — the script is unsigned but open source |
Q: Will this break other software? A: The only shared component is FlexNet Licensing Service 64 (used by Adobe). The script always asks before touching it. Generic file type associations (EPS, WMF, Ghostscript) are intentionally left alone.
Q: Can I remove just one product? A: Yes — use option [2] to pick specific products.
Q: Does it require a reboot? A: No. The tool achieves a verified zero-remnant clean on real machines in a single run.
Q: How much disk space will this free?
A: Typically 5–50+ GB depending on installed products and the C:\Autodesk staging folder.
Q: Autodesk installer gives Error 103. What do I do? A: Run option [10] Fix Error 103 — it performs a 9-point diagnostic covering ODIS lock files, debugger keys, service state, ODIS infrastructure, VC++ redistributables, and Windows Event Viewer analysis. Each issue found can be repaired with a Y/N prompt.
Q: My antivirus flagged the script. Is it safe?
A: Yes. The script is a plain-text .bat file — you can read every line in Notepad before running it. Antivirus software sometimes flags unsigned batch scripts that modify the registry. Add an exclusion or temporarily disable real-time protection to run it.
