IE may be your last resort. I have no idea why you keep having this problem. And, installing IE may not fix it - so then where are we?

My guess is that the MXOP program relies on some DLL that is not included in their install, and that MOST people already have on their system (maybe from IE).

That SCRRUN.DLL is the scripting runtime dll - and actually has a lot of features that programmers use. Installing IE would probably install that DLL.

I just went ahead and emailed you the scrrun.dll to see if you can install it and try it out.

Let us know.
