Hi. I konw how to control the Program Files path for Win XP 32 unattended install (ProgramFilesDir="*"), but since XP 64bit has got two program files folders(one for 32bit programs and one for 64), i don't know what to do ;( My setup is like this for XP32: C:\WinXP32 D:\Documents and Settings D:\Program Files (x86) and i want XP64 to be like this: C:\WinXP64 D:\Documents and Settings D:\Program Files (x86) D:\Program Files The "Program Files (x86)" folder containing 32bit apps and "Program Files" 64bit. Ps. is there a special "CommonProgramFiles" path for 64bit ? -Gnarr
