Verify/repair game files
Because Rockstar Games has largely moved on from maintaining the legacy code of GTA IV, the burden of fixing the VDS100 error has fallen entirely to the modding community. Over the years, a canon of fixes has emerged to mitigate the issue.
Sixteen years later, you can still boot up GTA IV , hear that iconic piano chord, then immediately be greeted by a VDS100 crash. It’s infuriating. But in a strange way, it’s also part of the game’s identity: Liberty City is a rough, broken, beautiful place — and so is getting the game to run.

Fixing the VDS100 error usually requires restoring the integrity of the game's file structure or bypassing problematic legacy requirements.
