Outlook Add-in Not Loaded. Runtime error

Hi,

i have an error in my Outlook Add-in, the only Errortext that i have is:

"Load Behavior: Not loaded. A runtime error occurred during the loading of the COM Add-in."

I know that many developers have the same problem, but I did not find a solution :-(

The Add-in works fine in on my developer machine, but not on my test machine (WinXP Prof. Sp2 Outlook 2003)

On the test-machine i have installed:

Install Framework 2.0

Install VSTO Runtime : VSTOR.exe

Office interop assemblies : O2003PIA.EXE

My installer also set the correct regestry keys and i have FullTrust (CAS) for the Add-in.

To get an errortext i tried this:

in cmd:

set VSTO_SUPPRESSDISPLAYALERTS=0

Then run outlook from that cmd line.

But no Error-Box :-(

Please Help me....

Please supply more details:

Is this a VSTO 2005 Outlook add-in, or a VSTO 2005 SE Outlook add-in

Which version of vstor.exe have you installed

Exactly what did you do to setup FullTrust CAS policy for the add-in What was the caspol commandline you used

What is your add-in doing Also, specifically, what is it doing in ThisApplication_Startup

I had a similar problem, and the following helped - Open up command prompt and give the following commands

C:\>set VSTO_LOGALERTS=1

C:\>"c:\Program Files\Microsoft Office\OFFICE11\EXCEL.EXE"

Set the environment and launch excel through the same command prompt - i think the variable is set as a local variable for that particular command prompt.

now you should have a log in directory where u placed ur plug-in dll. See if the log helps.

There's been no response on this post for a long time, so I'm closing it now. If you get any further problems with VSTO add-ins, please open a new post.
