This page is an attempt to dive deeper into some common issues and solutions listed on the wiki homepage. Please refer to that page for for other issues.

Issue: Failed to start process (the parameter is incorrect [87])

Solution: Check the options for the executable

Solution: Disable anti-malware and anti-virus programs

Issue: My mods don't show up in LOOT / Wrye Bash / xEdit!

Solution: Disable anti-malware and anti-virus programs

Issue: Switching profiles causes MO2 to crash

Solution: Disable anti-malware and anti-virus programs

Issue: Browsing for a file or folder causes MO2 to crash

A crash in this manner is usually caused by a program that creates overlay icons on files. This is an incompatibility between these programs and Qt, the GUI framework used by MO2.

A known offender of this is software for Alienware or Dell computers that may be called Alien Respawn or Dell Backup and Recovery. This comes stock on many of their computers. Installing the most recent version of this software should resolve the issue. Alternatively, uninstalling the software should also fix the issue.

Solution: Check the options for the executable

In the Modify Executables dialog, double-check the "start in" and "arguments" fields for the executable having problems. The possible problems are too numerous to list here. If you're not sure what they should be, maybe ask in the Discord channel.

Solution: Disable anti-malware and anti-virus programs

USVFS hooks into the programs you run through MO2. To many anti-malware programs, this can look like a nefarious action. Many of these program will interfere with MO2 or USVFS with absolutely no indication to the user. Adding exclusions or exceptions to the entire MO2 installation folder, not just the executable, may allow MO2 and USVFS to work correctly. Some particularly stubborn programs seem to not respect exclusions and may need to be completely uninstalled.

Note: Not all users will be affected by this in the same way.
Note: This list is non-exhaustive. This only includes programs we've seen interfere.
