Word 2007 VSTO add-in loads slowly if no internet connection

[edamron]

I have a ribbon add-in that takes up to 40 seconds to load on PCs
without internet connections. On computers with an internet
connection it loads in about 1 second.

Platform information:

The add-in uses VSTO and was created for Word 2007 using Visual Studio
2005. It is being run on Windows XP with SP 3.

We put a packet sniffer on that PC and found that the add-in was
trying to go out to crl.microsoft.com and had to time out before it
would continue! A solution is documented here:

But as I understand it this would disable the check for Certificate
revocation for everything. My supervisor has made it clear that this
is not an option.

I continued to search for a different solution and found that I can
modify the app.config.xml file by adding the following xml:

<runtime>
<generatePublisherEvidence enabled="false"/>
</runtime>

At first I thought that this was the solution. It seemed to work.
But I discovered that it only works for the person who installs the
add-in. For all other user accounts the add-in still loads very
slowly if there is no internet connection!

My supervisor is treating this as a "show stopper" so I'm under
enormous pressure to resolve this issue. Can anyone offer any help?
Please!?

Thank you.
