Erm seems like these are for 64bit os systems only..... taken from the readme info on station drivers site it says CATALYSTâ„¢ Beta 2 for Windows XP 64 bit for AMD64 And a little further down it says Known Issues This section provides information on known issues associated with the CATALYSTâ„¢ Beta 2 for Windows XP 64bit for AMD64 video driver. Sorry if Im wrong but thats what the info is saying.
