I concur with your observation.

The add-in works on two machines both of which have VS 2005.

The add-in fails to load on a third machine which has a similar baseline but
no Visual Studio.
This machine of course has been equipped with the 2003 Primary Interop
Assembiles and the VSTO runtime.

So what is the missing ingredient?

Now I found that the add-in developed in visual studio 2003 works on
all the machine, but the add-in developed with visual studio 2005 works
only onsystems which have either visual studio 2003/2005 installed.
So, is there any specifi dependency for 2005 Add-in? ("other than
the .net 2 framework requirement.")

Am i missing any dlls on which outlook add-in dependens. (My test addin
is simple one line application, it pops up the Hello World message box
on startup).

Usually that happens if the addin is not fully trusted on the target
machine, something that's required and usually requires a custom installer
action.

I have the same problem so let me describe it in a little more detail.

Two systems have the the Outlook Add-in installed.

One PC works fine, the other fails to load the Add-in with this text
"Load error. A runtime error occurred during loading of the COM Add-in"

Where may I find more information about the runtime error?

The systems have similar SW baselines

XP Pro SP2
.NET 2.0
Outlook 2003 SP2
VSTO 2005 runtime
Office 2003 PIA's

Another post suggested that I disabled CAS but this doesn't help.

Registry looks fine excpet of course the Add-in's Loadbehaviour is changed
from 3 to 2.

I do not have vish's problem locating the Add-in thru Advanced options|COM
Add-ins
but it is unchecked.

Regards
Peter
