reinstalling win98se
 

The relevant computer (not this one!) is an older HP laptop with
Win98SE, 650 MHz PIII and (I think) 256MB of RAM. I bought the system
several years ago as a used item (not a good investment -- I wouldn't
do it again).

I installed a program that has unfortunately corrupted the operating
system. The message I get is:

The OLE32.DLL file is linked to missing export ADVAP132.DLL:
DuplicateEncryptionInfoFile

The system then says it can't use Windows Explore.

The problem is, I can't get into the system to fix it. I don't have a
boot CD ROM, and I tried creating one from an .iso file I downloaded
from the web, but it created nothing I can use. I can't boot from the
resulting disk. I'd be happy to just reinstall Win98SE on the
computer, but I can't get anywhere without booting from the CD ROM.

Suggestions?
