Out of the blue when I started my laptop (Dell D600, Windows XP SP2) I started getting the following error:
Wireless Configuration
Incorrect MFC DLL version installed on this system; minimum requirement is MFC SP4 Dlls.
The message wouldn’t stop popping up, rebooting didn’t help.
Solution
Google was not much of help there. The best advice found was this; it didn’t help though. Finally I decided to remove Dell Wireless Manager because… it had the same icon that this annoying pop-up 
This helped!
At the moment I can’t do much more about the wireless because my router is in the service. When it’s back I’m going to reinstall the software for wireless and I hope all works grand. If I have any problems I’ll update this post.
