When upgrading to the latest on your site, it would not install. I got the error message that the OS needs to be at least vista.
I have a windows 2003 R2 SP2 that I run on and the license is tied to. This machine is isolated from others and needs to continue to run. Could you remove the OS restriction?
We recently upgraded our Microsoft development Studio suite (from the old 2010 Suite) to take advantage of better performance, fewer crashes, improved stability, and compatible with new Windows 10. Unfortunately with each Studio suite upgrade Microsoft forces the applications to run on newer versions of their Windows. There's nothing we can do because this is a Microsoft forced feature, and yes it is also frustrating to us as developers.
I would be happy to provide you with the previous versions of FAB 3000 and ACE 3000 that still used the 2010 Developer Suite (and will continue to run on Windows 2003).
