Illegal Operations Error In Outlook

Carey…can you advise me? When I open Outlook I get an error message that says I have performed an illegal operation. When I close it for
the 2nd time I get the following:

The add-in “ZFEXT.DLL” could not be installed or loaded. Unable to load “ZFEXT.DLL” You may be out of memory, out of system resources, or
missing a .dll file.

What should I do?

Carey’s Answer:

Open Outlook.
Go to Tools, then Options, then click on the “Other” tab. Click on the “Advanced Options” button under “General.” Next, click on the “Add-In Manager” button in the group of buttons above the “OK” button.

Zfext.dll is a dll (shared utility) file for ZipForm in Outlook. When you uninstalled the stand-alone ZipForm application, Outlook was looking for Zfext.dll in the wrong place. Uncheck the box beside “ZipForm 5 Outlook Extension” in the Add-In Manager window. You should be able to open Outlook normally.
