COM Add-ins not installing

[Chris Roth [ Visio MVP ]]

Hi all,

I recently installed some sort of Office patch or update on my system.

Since then, when I build COM Add-Ins for Visio, they don't run on other
people's machines. I can still install and run them on my machine, but they
don't work on my Virtual PC, or on other's machines. The install works fine,
but nothing runs.

I noticed that I had to re-reference Visio and change the Imports from
"Microsoft....Interop.Visio" to just plain "Visio", or leave it out
entirely.

Anybody else had this problem and come up with a solution?

Hey Chris,

It sounds like your Visio PIA isn't being referenced anymore. This could be
a side-effect of the update you installed, or the result of running an older
version of Visio alongside Visio 2003...if the older version was run last,
Visual Studio references the wrong typelib and generates it's own IA.
Before you add the Visio reference in VS, run Visio 2003, and if that
doesn't work try doing an Add/Remove/Repair to see if that sorts out the
problem. Let me know if it's still not working.

Make sure you're installing Extensibility.dll. This one threw me for a while
until I had found that it wasn't included. You don't need to register it,
just make sure it's in your installdir.
