1.1 Add-in fails to load on 2.0 system

Good Day,

I have a .NET 1.1 IDTExtensibility2 add-in written for Word, Excel, and PowerPoint 2003. It's shimmed using a COMShim Wizard generated shim. We're in the final phases of development and I am currently testing deployment.

We tested deploying to systems that have the 1.1 Framework installed, the 2.0 Framework installed, and both installed. In most cases the add-in works fine.

However, on one system that just has the 2.0 Framework installed, the add-in fails to load for Word and Excel but strangely enough, works just fine in PowerPoint. The "LoadBehavior" reg key gets set to 2 as soon as Word or Excel starts so the add-in appears to be crashing immediately.

I’ve confirmed that problem system has the Office 2003 PIA’s installed and the COM Shim appears to be properly registered. Does anyone have any ideas on what could be causing the problem or how to possibly troubleshoot this

Thanks,
