My solution didn't work, went with the old solution and I am now executing FAForever.exe as admin.
Had the same problem like there (short of the virus - never had a virus on my PCs

when starting got an Error with Permission Denied to open FAForever.exe.log
I didn't do a reinstall.
I gave user full control of the FAForever.exe.log (it's in the main FAF install folder)
after that I got an error with the info that the error code is in FAForever.exe.log
The error code:
- Code: Select all
Traceback (most recent call last):
File "main.py", line 44, in <module>
File "util\__init__.pyc", line 146, in <module>
File "logging\__init__.pyc", line 1511, in basicConfig
File "logging\__init__.pyc", line 893, in __init__
File "logging\__init__.pyc", line 912, in _open
IOError: [Errno 13] Permission denied: 'C:\\ProgramData\\FAForever\\logs\\forever.log'
Gave user full control of forever.log and now it seems to work.
Hope I could or will help someone with this information
