yup reinstalled it, crc of exe matches that on cd, it must be getting changed or something in memory.. wish microsoft documented the dep crap a lot more like its 'internals'.. as im beginning to suspect thats whats causing it... or somethings patching the exe in memory and it isn't matching the file on disk... odd, odd odd... i'll see what happens in vmware at the weekend.. see if that sheds some light on it...
