For some reason i can't do anything on the PC, before this i installed Internet explorer 7, i had to reboot and now i get this error. This application has falied to start because Normalis.dll was not found Re-installing the program may fix the problem.
If you have your OS then you can do a Windows repair. You won't have to reformat and reinstall everything. Try that and see if that works.
Hmm.. Looks like you had a virus/trogan located in that file, and you AV prog's took it out. Theres not much you can do without explorer.exe, your going to need to re-install. Sorry bro.
