Hello folks,
I took the tiger by the tail and spent some time searching the internet and Microsoft support trying to find the answer. I figured out what the problem is (was now that I'm running K-Meleon to write this message). You get that error MFC42.dll:6491 if you are using too old a version of MFC42.dll. K-Meleon needs a newer version (at least the one found in Windows Millenium). You can download a version of MFC42.dll that gets K-Meleon up and running at the following web site:

Installation is tricky though. You have to unzip the file and shut down to DOS. Move to the folder you unzipped MFC42.dll into, for example c:\windows\desktop and copy MFC42.dll to your system directory. Say yes to overwriting, reboot and your done. K-Meleon should now work. Assuming of course there aren't other files that are too old to run K-Meleon.
