98 upgrade UNREGMP2 & PNPWPROP.DLL
colerml May-24-01 07:35 PM
I am upgrading from 95 to 98 and having the following problems. I receive two messages during the upgrade:

UNREGMP2 has performed an illegal operation

Cannot load PNPWPROP.DLL for the tape hardware being installed.

The upgrade completes, but when windows reboots I get past the windows login screen then get an

EXPLORER.EXE illegal operation message and cannot load windows.

Any suggestions to get past this? I have tried reinstalling with the same results.

If you saved system files during the first install, see if you can remove Windows 98 in Start, Settings, Control Panel, Add/Remove Software, which will restore your old operating system. In any event, make a directory C:\windows\option\cabs and copy D:\windows\win98\*.* to it, where D: is your CD-ROM. You may need boot to Safe Mode, if possible, or make startup floppy (see our how tos) to do so. Then strip the computer down to just that required to install Windows, Hard Disk, no other drives, and no boards except video. You may also want to disable all unnecessary motherboard devices in the CMOS Setup. Install Windows from the hard disk by:
C:\windows\options\cabs\>setup /ie
Windows may try to install to C:\windows.000. Edit it back to C:\windows and ignore the warning. If you get a good install, start adding things back one at a time. Larry

Larry,
When you say strip down, do you mean to physically disconnect these other devices or do you mean ro remove any reference to the drivers in the system files?

Physicaly remove them so Windows won't detect them and possibly choke on them while you are installing Windows. Larry
