1. http://www.google.com/search?hl=en&lr=&q=xp+%22compatibility+mode%22&btnG=Search Did you try all options?
2. Convert from XP Home to XP Professional on your 'other' machine. It's a superset, so you shouldn't lose functionality.
3. Try Vista
4. Contact Symate Plus customer support
5. Go and buy a XP compatible program for coding PLC's. DOS support is fading away.
6. Any second hand machine able to run DOS 6.0/Windows 3.1 should suffice. They are very CHEAP. Buy a KVM-switch so you can share keyboard, mouse and monitor. The box the program runs on isn't important at all; the user interface should be all that matters.
Hope this helps.
PS. Maybe someone else can help you to get this running on XP Home. Sorry, but I can't.
I have an old DOS program called Symate Plus (Square D) for coding PLCs.
(It dates from about 1993.)
On one computer running XP Professional it runs fine, either in a window or full screen.
On my other computer running XP Home it starts okay but the ten function keys won't work. (The program is accessed via the function keys.)
I've tried everything I can think of to get it working on my other computer but without luck.
Can anyone help with this?
