Actext.dll add-in error opening Outlook

By melinayung ·
I upgraded a PC from 98 to XP Pro. It has Office XP on it and when I open Outlook i get the following error message:

The add-in "C:\Windows\System\ActExt.dll" could not be installed or loaded. This problem may be resolved by using Detect and Repair on the Help Menu. Unable to load "C:\Windows\System\ActExt.dll". You may be out of memory, out of system resource, or missing a .dll file.

It has 128 MB ram, its a Celeron 1.3 ghz. I've tried to re-install outlook, re-intall office, done detect and repair and also un-installed and re-installed Norton Anti-Virus 2003, but nothing will get rid of this error.

Once the error comes up you can press ok and continue to use outlook as normal (or so it seems) but it's an extremly annoying message.

Please help!

It seems that you added a component to your outlook.

Explore registry to find any occurence of actext.dll, and remove it.

Re-install won't help because registry keep in memory add-in previously installed.

I searched the registry for the dll and found it was part of a program which has an add-in in outlook, so i just turned this add in off using the tools, options, other, advanced, Add-in Manager and un-ticked that program. Alls running fine now.

Thanks for your reply though.
