I made a simple script that will help you get rid of this problem.

:: A free script to fix the Windows 11 24H2 error,
:: due to which 3ds Max does not see user scripts, macros and plugins.
:: The script removes system/hidden attributes from AppData and Local,
:: and also automatically corrects paths for all installed versions of 3ds Max.

this bug in Windows 11 24H2 is due to the fact that Max in new builds uses useUserProfiles=1, and as a result, usermacros and scripts go to %APPDATA% instead of the local Max folder.

.bat actually:
Makes the AppData folder visible.
Backups usermacros to a separate directory.
Changes useUserProfiles=1 to useUserProfiles=0 in InstallSettings.ini.
Run as an administrator!

Thank Elvis,

it completely broke down my 3ds Max, I now have to run it as administrator, so I can only open scenes if I open a fresh Max, otherwise I get a shit ton of errors for missing files/plugins/dlls and what not. I also constantly have to re-do the UI because it resets to default.

Can you suggest a method to revert what you did?

Because I can't work like this I'm thinking of re-installing everything.

Cheers
