We are receiving customer-reported issues that the newest version of our add-in is failing to load in Outlook 2007. Our add-in is built with the latest version of Add-in Express 8.7.4430. This seems to happen on systems with Windows 7 and Outlook 2007 only. Is this a known issue in Outlook 2007? We weren't seeing this issue with 8.6.4408.0.

Adxloader.log below:

Hello Douglas,

Please find out the add-in unchecking which in the COM Add-ins dialog prevents the issue from occurring.

I'm not sure I follow what you mean. I don't currently have access to any of the PCs that were displaying the error.

Hello Douglas,

The issue is quite serious. I suggest that you turn off all of the other COM add-ins on an affected machine. Then, you turn them on one by one to find the add-in with which the issue is reproducible.

We need to know the name of the add-in as we (most probably) need to contact the vendor. For the time being, your only workaround is to turn that add-in off until we contact the vendor and find a solution with them.

You may prefer to discuss any details outside of the forum. If so, you can send us an email to the support email address; find it in {Add-in Express installation folder}\readme.txt; please make sure your email contains a link to this topic.

We've already determined that our add-in is causing the error. We are the vendor. :)

I'm unable to repro this locally. We've only seen this in customer environments: Windows 7 and Outlook 2007.

I'll email you at the support email address.

What I'm trying to tell is this: there's one more add-in that you need to turn off in order to let your add-in work.
