can't make Megui work on 2comp's after virus

[junglemike]

Hello. I had a virus on my home network, which corrupts some files.I've cleaned the virus, but Megui stopped working on both computers which were infected. I get this error:

I've tried first repairing .net framework 2.0 and than uninstalling both .net framework 1.1 and 2.0, and also uninstalled and reinstalled Megui, and it still doesn't work no matter what I do.
Both computers run Win2000, I also have old laptop, which was not infected, and also run win2000,and have megui and .net 2.0 installed and working,
I would like to copy the files from the laptop to the rest of computes, I tried copying whole megui folder, but it didn't work.
What else can i do?
TIA

The best solution, would be a complete reinstall of the OS, especially when you don't know which file(s) are corrupt and/or missing. There are most likely other issues that you have yet to find.
