COM Add-in not loading

[Jack]

I have a workstation that refuses to load a COM Addin. It is running
Outlook 2002 on Windows XP. The Addin is registered (I actually
unregistered and re-registered it to make sure), it is not in disabled items
and loaded fine in the past. I try to add it via the
tools-options-other-advanced-com addins-add and it allows me to select the
addin but never adds it. This Outlook installation was recently reinstalled
(Office was actually reinstalled) due to a significant level of instability.

What else can I try? There are no errors when I attempt to load it it just
does not show up.

I don't know much about Outlook, but if it's similar to Word your add-in
might have been deactivated if it messed up previously. In Word, there is
an option in /Help/About to activate deactivated add-ins.

I believe that is the same as the disabled items in Outlooks help-about, and
it is not listed there.

Thanks for the idea,

If HKCU (or HKLM)
\Software\Microsoft\Office\Outlook\Addins\<Your_addin_name_here>\LoadBehavior
is 3 the addin should load. If it does not that means it probably encounters
fatal errors when it connected. That means you need to get a fresh copy of
the installer and try that.

If you have access to the source code you need to run it in debug mode and
look for errors in On_Connection and so on. It might be some DLL or OCX that
was removed or unregistered.
