A friend has a problem with his PC that he has kindly passed to me to sort out for him.
Previous to this error eing reported the system was working fine. The system boots and performs POST etc fine, the windows logo flashes one or twice as things are loading, then a red DOS box appears titled NAV Auto-Protect with the following message "Unable to determine the location of the configuration files". Pressing OK allows you to continue and the background wallpaper appears followed by a box with the following error "Explorer caused an invalid page fault in module EXPLORER.EXE".
That is as far as it get's, the same happens in safe mode. I have run scandisk, defrag, diagnostics disk, put the hard drive into another machine and virus scanned it and no problems reported. I have tried the step-by-step config and stopped Norton running but no luck, does exactly the same just doesn't show the NAV screen. The only thing I haven't been able to do is run Scanreg from DOS, just says Bad command or file name. I am reluctant to re-install as although he has the disk he can't find the product key anywhere.
Any ideas anyone ???
