Error suggests advpack.dll is blocking installations. I have tried manually changing all (11) advpack.dll versions in system32, i386, dll cache, etc, to various other versions. When I started this, had v. 6.0.2900.2180 published 5/8/05 in two locations, and v. 7.0.6000.16512 published 4/25/07 in others. Have tried making all v. 6.0.2900.2180, all v. 7.0.6000.16512, and even tried an older version from 2004. No change, same error.
Then tried removing all advpack.dlls, just for the heck of it. Not hiding, not renaming, I removed them all to an external disk and turned that disk off. Thorough search shows no advpack.dlls in system.
After reboot with all known advpack.dlls removed, on attempting to install updates, I get same error - Reason is advpack.dll in system32. There is no advpack.dll in system32 or anywhere else!!! I removed them all. I checked before and after. It had not been mysteriously replaced from or to anywhere on system. advpack.dll is nowhere that I can find on this machine. Yet, the error says advpack.dll in system32 is the reason for the error.
This happens with all XP, MS related updates. I tried autopatch for August 07, sadly the last autopatch there will be. It installs the updates, sort of. They are listed in add/remove as installed but with yellow exclamation icon and all are .75 MB in size. This is true of security and other updates, however .NET 3 installed fine via autopatch, apparently.
BTW, web references for advpack.dll state that it is required for proper operation. Either I have missed removing some of the advpack.dlls or it is not needed.... because obviously the machine is working fine.
Also, all third party installations work without a hitch. No other known issues.
It was not long after advpack.dll v. 7.0.6000.16512 was installed (4/26/07) that this problem started. Please note however, I replaced all advpack.dlls with older version, and still installation of updates failed with same error message. What package was this .dll a part of?
Suggestions? I've searched around, and tried what I could think of?
