The following problem is occurring on PCs running Windows XP SP3.
We have been running some petrologic programs from KWARE (Heat3d, Magma, KWDraw) on our student computers for a few years now. Last week I installed AutoCAD Map 3D 2010 on one of the computers. Now every time I try to open a KWARE program, the AutoCAD configuration runs. I have to cancel it four or five times before it will finally open the KWARE program. This happens even when I've already configured AutoCAD by opening it directly. I tried uninstalling and reinstalling the KWARE programs, but no joy.
I recall having a similar problem a few years ago, where the WordPerfect setup ran when I tried to open an unrelated application. But I can't remember what I did to fix the problem.
