The profiles are just 'data' in the sense that a document, spreadsheet or even image is data, in otherwords they should be underlying O/S agnostic.
I have no problems uploading or downloading profiles from my Z3100 to either Win7/64, Win7/32, XP or Mac OS X....
Thanks very much...one more wuick question if you don't mind. If one is using 64 bit Photoshop on 64 bit Win7 should the profiles be in c:\windows\System32\spool\drivers\color\ or in c:\windows\SysWOW64\spool\drivers\color\
What about if you are using the 32 bit PS on a 64 bit Win 7??
Why do they have folders for both 64 and 32 bit profiles?
