Thanks. Btw i even tried with vanila VC and it crashed when the cutscene ended (Even skipping it will crash). I will try to do your method.
EDIT: I don't have Vice City installed on Program files, i have it on D: drive since C: is full. But i found modloader folder in appdata/local.
I didnt said C: or D: Just go to Appdata > Local > VirtualStore
You will find Rockstar games folder in there
