Shell32.dll

I have installed all pertinent updates from Microsoft. I had already
installed IE6sp1 on my Win98DE desktop, but had to get a disc from Microsoft
because I must use a dialup modem because of my physical location. When I
visited the .dll help site recommended by Ron, I saw where one specific
shell32.dll was used for IE6. I checked the file present on my computer,
found the ver#, checked that against the help page, the two #s didn't match.
I had to find someone else with the listed version, he sent me the file, I
installed it in place of the older version. After rebooting, the new program
still wouldn't recognize the shell32.dll.
The old ver was 4.72.3812.600, the new ver is 4.72.3612.1700 (listed as
being for IE6sp1). I believe I installed IE6 originally because of the need
for that ver of browser because I wanted to use this new program; now that I
have it, the program won't install! Maybe my copy of the new program is
flawed! I have no other problems with anything on this computer, not with IE
or OE or anything else I normally use. I'm mystified, and the new program
owners don't have anything helpful to suggest.
