I'm bringing up a Mach3 controlled lathe using an XP machine with SP2 loaded.

Mach3 runs fine on it but I need to tweak the screen and when I try to run Screen4 on the machine it craps out after loading the screen.
It puts up a bunch of error message boxes but they don't have any message in them so I can't tell what wrong.
The machine is pretty stripped down with hardly any other apps on it and screen4 runs fine on my office machine.

I need to be able to run screen4 right on the machine as I need to tweak some of the hotkey settings and so I need to run right on the machine that has the ipac based machine controller on it.

Do I have to put an additional runitime library or dll to allow screen4 to run on the machine?

In Screen4, click on Defaults, and point it to your Mach3 installation folder. Each of those message boxes is because it can't find a bitmap.

Thanks Gerry, i did install mach to a different directory name so that was the problem.
