Not a valid Win32 application in MSN

[Anwar]

Hello Friends

I'm unable to run MSN Messenger on my system. It shows me an error that it does not have a valid Win32 application. Can any one help me out with this problem?

Thanks.

Hey check out whether you have a root directory and see if you have a file autorun.inf You may need to go into the DOS window and use dir/a *.inf

Hey try to uninstall and then re-install your MSN messenger again. If you face the same problem again then try to repair your operating system, may be some of it files may have corrupted.
