error when opening addin manager

[jeremy]

I am using autodesk inverntor 2012 on a Windows 7 x64 sp1 box.

When I try to open the addin manager, I get an error 

Could Not Process AddIns.

Check if you have the compatible Comcat.dll from Microsoft (NOT Version 5.0).

See Microsoft's Knowledge Base on 'Mismatched Ole32.dll and Comcat.dll'

The knowledge base article I found on MS site is old, and talks about windows 95.

Currently I have Comcat.dll version 6.1.7600.16385, Ole32.dll version 6.1.7601.17415 on my system.  This error started occuring after we upgraded the network from a p2p to a client/server network, using server 2008 r2.

Autodesk update No. 12 and Service Pack 2 for Autodesk 3dsmaxdesign suite were applied in December.  This error only recently started occuring.

Welcome to the forum.

I don't know if this will help you, but you may have a bad install as a result of the server change.

Have you tried going to your control panel and under install/uninstall programs doing a repair?

I have the same issue with Inventor Professional 2015. I am running Win 7 64-bit. Everything is patched and up-to-date.

I have tried probably all different options of uninstall, reinstall, repair, turning off UAC, turning off anti-virus, running the installer as Administrator, and whatever else I can think of.

Can you provide a step-by-step instruction on how to fix the problem?

Thanks.

Thank you.
