win98 MFC42.dll problem

My 80 year old parents are quite happy with win98 and the apps they
use. i thought i would 'help out' by installing apache and then adding
some other stuff.
After installing apache and php , Paintshop Pro v5 and v7 fail with a
IPF mfc42.dll error .
things that havent worked :
ive removed apache and php ( through the control panel) and rebooted
and then
Ive reinstalled PSP 5 and 7
Ive reinstalled mfc42.dll from the CAB file ( v 4.21.716.0)
Ive the latest one ( in c:\...PSP7\ ) and copied mfc42.dll
(v6.00.8665.0)to c:\windows\system and rebooted

anyone any other ideas

there are a load of Apache registry entries still present. Is there an
idiot-proof way to remove them all ? Will it help ?

If you have removed Apache completely, you may wish to go after the remnants
in your registry file. Be careful on this one and only delete what it will
let you AND, most important, only those items that have the pathways to
those programs you have removed. click on start ---- run ---- enter
registry and click on okay. Then click on edit and search or find. Search
for only those entries that have the pathways to the programs you have
removed. If it won't let you remove it don't worry about it. Just remove
the ones that you can. But be careful, removing of registry items that are
needed can get you a paperweight pretty quick.

The best thing, though, is to back everything up and format c:. In
otherwords, start over with a fresh copy of windows. Or, if you don't wish
to format c: then reinstall windows in a different directory and reattach
your external probrams.
