"Application load error 5:0000065434" when launching Steam version
Only happens when launching the game through BFBC2 Mod Loader. Probably caused by Steam's DRM. Will be investigated.
Note: Launching the game through BFBC2 Mod Loader is not required to make the mods work. Just launching the game through Steam is enough.
Workaround: Add BFBC2 Mod Loader as a non-Steam application and launch it through Steam. Note: Reported by an user. Seems not to work for everyone
Did what you said but still encounter the error as admin and as non admin i get error 53
Same issue as Husko, adding as non-Steam app results in an error when clicking Start Game in BFBC2 Mod Loader 2.0.1:
Steam - Game Launch Failed Battlefield: Bad Company 2 failed to start (error code 53)
The workaround was shared by an user. Needs further investigating then.
