...and it won't work on Win 8.1, then I'll guess it won't work on the newer Windows 10. Still, Windows 10 is currently out for Beta testing and if you've got a spare computer, or a friend that has a spare computer, you could surely install it and test out Quicken. The download of Win 10 is free. Other than that, there's really no way to know about specific program compatibility primarily because Windows 10 hasn't been fully released yet.
Hope this helps.
I am running Windows 8 and have not upgraded to 8.1 due to problems with a certain program not working with it, the program in question is Quicken 2004 which when I tried earlier (with 8.1) it refused to load so I had to revert to 8 I have records on this program going back nearly 20 years and I don't want to lose them so when I get the invitation to upgrade to 8.1 I don't take it up which takes me onto Windows 10, on previous upgrades there was a program you could run which scanned installed programs and let you know which ones would or would not work, is there such a program for W10, so to sum up how can I avoid losing my Quicken Data if I upgrade to 8.1 and will Quicken 2004 work with W10, you may ask why I am still on Quicken 2004 well that's the only one available in the UK
