Start as admin

I would not run as admin. Rather the permissions on C:\ProgramData\FAForever\bin\ForgedAlliance.exe have gotten messed up so that you need admin to run it.

Fix those permissions so you do not need admin to run it.

How do I fix those permissions?

I've set Full Permissions for the exe and every folder above it for all users, but the same error occurs.

I know I can fix this by starting as admin, but I'm trying to avoid that annoying pop-up every time I launch.

(I've deleted everything and done a clean install since the last time I started as admin.)

Edit:

Worked out a solution:

Create a new ProgramData folder in a different drive, set FAF to use that one.

@auroraraven said in cannot launch supcom:

How do I fix those permissions?

Try in Admin CMD:
icacls "C:\ProgramData\FAForever" /reset /t /c /l
