I still have the 200e and v4. Haven't had a chance to try yet, but I have the v4 software on an old laptop that lives near the sm. I have upgraded my other 2 computers to W7 and plan to do that one too as I'm networking the house (I know, serious geekdom but it keeps me occupied.) W7 Ultimate allows you to run XP software, all my old XP stuff stayed put and runs fine. In fact, my old, old, old DressShop which was written for W2000 is running fine on W7! The only thing was that it transferred all my Office 2007 Professional, including files, except Outlook disappeared. All the documents and all that stayed, but the saved email in Outlook went away.
I was assuming the v4 would run on the Ultimate W7 just because it is running all other XP software fine. All the versions of W7 do not run XP, however, so be very careful. That is actually one of the reasons I went with Ultimate.
Be VERY careful when you choose which version of W7! VERY careful! AND be absolutely certain to run the compatability thingie it prompts you to go online and do first, before you upgrade. All the versions of W7 don't run XP, but more importantly, some will wipe clean your hard drive and do a clean install, even when upgrading, and some will not. The hang tags at the store, at least where I bought my first one (Office Depot, which has the standard Microsoft shelf label info) does not IMHO give adequate info about the differences between the versions. I bought the middle one, Delux or something like that, and got it home. Went to do the upgrade, and was running the compatability thing while I went through the book that was INSIDE the package. Turns out that version does a clean install and wipes off your hard drive, while the Ultimate version does a true upgrade. Sure, I save everything, but I've been computing for twenty plus years and have a ton of back stuff, and like I said some things have managed to translate up from W2000, and all kinds of photos and favorites and all are there, and it is quite a pain to redo if they'll just stay put. Plus I wanted specifically to be able to continue to run XP software, as although I had Vista on some computers I had XP on others. I called Microsoft and they were quite nice about it. Told me where to mail back the software, with receipt copy, to get a refund of the one I bought in error. The refund came promptly and I bought the right one. Love it. K
