|You can get many programs meant for operating systems older than XP to run by using a compatibility mode. RIGHT click on the program file that starts it, choose Properties, Compatibility, choose a compatibilty mode for an older operating system. Then use the shortcut that procedure makes to start the program, rather than the original program file, when you want to use the program. The shortcut is created in the same folder as the file you RIGHT clicked on - intially at the end of the list of files in that folder, then after you exit and re-enter that folder, it's in the list according to the way the list is sorted - by default that's alphabetically.|
You may also have to do that when you install the software, such as for it's Setup and possibly a configuration program.
If the program is a Dos one, if none of the compatibility modes work for it, there are freeware "dos box" simulation programs on the web you could try.
