I can't launch after the Feb. 2025 patch even after an uninstall and a complete reinstall. I ran the fixer and still get the following error:

Have you tried to contact the MWO Tech Support?

Didnt see this one.. post from Feb. Most likely issue was his antivirus program "quarantined" the file when it was updated due to not having it marked as safe. Have Antivirus/Security program restore it, exclude gaming folder from active scanning then if necessary use the MWO Repair Tool.
