Hello peter tolcser!
Thanks for reaching out to Microsoft Q&A forum.
Here’s what you can try to uninstall the AutoDesk software that's being blocked by Smart App Control:
Option 1: Temporarily turn Smart App Control off
Important note: SAC can be turned off anytime but turning it back on later requires resetting Windows. Make sure to back up important data first, just in case.
Then go to: Windows Security > App & browser control > Smart App Control settings > Off
After turning it off, retry the uninstall.
Option 2: Manual removal (advanced)
If you’re comfortable with technical steps:
- Press Ctrl + Shift + Esc > Task Manager > End task on any Autodesk processes.
