outlook 2003 add-in fails to load

[Marc]

Wrote a simple addin with VSTO. Runs beautifully on my machine that has VS
2005 and VSTO installed, and on another dev machine also with the VS2005 &
VSTO installed. It won't run at all on any other box. In the advanced
properties of outlook, it mentions a failure trying to load the add-in.
I've installed what I believe were all pre-reqs, including the VSTO
run-time, the .net 2.0 framework, and the interop libraries. Any help at
all is appreciated!

Most likely the assemblies you are using don't have full trust. That's
required for them to actually run when deployed.

Read the 2-part article starting at
http://msdn.microsoft.com/office/de...a/html/OfficeVSTOWindowsInstallerOverview.asp
for information about how to add trust to your addin installation.

problem solved (thanks Ken for pointing me in the right direction). It was
code access security. This command did the trick:

caspol -u -ag All_Code -url C:\<FolderName>\<FolderName>\* FullTrust -n
"<Name>" -d "<Description>"
