I never has this problem with XP. I need to add a parameter to the Fear Cry shortcut, -devmode, to get a trainer to work. Vista Business keeps telling me this:
The name 'C:\Program Files\Ubisoft\Crytek\Far Cry\Bin32\FarCry.exe-devmode' specified in the Target box is not valid. Make sure the path and file name is correct. I have tried making a new shortcut, but that did not work either...
