I am still using this ancient Supercharts program. For 3 reasons. First - I own it (many current programs are "rental" only or cost a ton of money). Second - I have decades worth of compatible data (some going back to the 1930's). Third - it works for me

I - like the OP (and others) - tried to get the program to run on Windows 7. And it wouldn't. The primary problem had to do with graphics compatibility. And - although some gamers who liked old games were able to find workarounds in Windows 7 (I read many obscure computer gamer discussions at the time) - none of those workarounds worked here.
Anyway - I uninstalled Windows 7 (it came pre-installed in my newest computer) and went back to Windows XP. And I'm still using Windows XP. Support for XP has been discontinued. And that newest XP computer (a 5+ year old Thinkpad) is getting cranky. So I installed the program on an even older Thinkpad that I don't use for anything else. So far - so good - but for how long? Hardware doesn't last forever.
I really don't know much about operating systems. Is there any reason to believe that a program that didn't work in Windows 7 would work in Windows 8? Or even Windows 10? Robyn
*I tend to stick with programs if they work. I'm still running a DOS program - Managing Your Money. It did work in Windows 7 and I assume it would work in later versions of Windows if DOS is somewhere in the OS.
