Hello I purchased a daw from dancing dots a few years back which is running xp. I know that I need to upgrade to windows7 but I'm not sure which version I would need. I'm now using xp professional with jfw 12, sonar 8.5 and caketalking 8.8 I think is the latest. I did see a windows7 home premium 32 as well as 64 bit. Also, windows7 professional 32 bit. Thanks for any help.
