My addon does not use the inf to copy the files to system32... It uses txtsetup.sif, look at the entries.ini. The inf is used only to add the shortcuts (also its used for uninstall) AeroSide.exe = 100,,,,,,,2,0,0,Aero_Sidebar_Clear.exe LongSide.exe = 100,,,,,,,2,0,0,Aero_Sidebar_Longhorn.exe VMPlayer.exe = 100,,,,,,,2,0,0,Vista_MiniPlayer.exe I just tested this addon again and nothing is wrong with it EDIT: That INF you posted above is not my INF file. No clue where you got it from or who the hell moddified it
