Webuser Forums: COMDL32.DLL SHLWAPI.DLL ERRORS?

I have an Dell XPS T600R which I've owned since 2000, initially Win '98 was installed, this was updated with Win ME some years ago, the machine is currently used as a base unit for my wireless router/broadband modem, my main source of Internet access is via my laptop.

The reason for the post is I've started receiving an "Error Starting Progam" message as follow:

"The COMDLG32.DLL file is linked to missing export SHLWAPI.DLL:SHRRegGetValueW."

I couldn't fix the problem after many hours of searching, eventually tried installing Win XP but received the following message "The File C:\Windows \WINNT32\WINNT32A.DLL could not be loaded or is corrupt"

I no longer have an ME discs only the original Win98 discs which were supplied with the PC. I am able to access certain areas on the PC, Internet access is possible via IE but not Mozzila, error message appears when majority of programs accessed.

Any assistance would be appreciated, I am no expert but would like to fix this problem as easily as possible.

Regards!
