Shared Addin problem

[TonyR]

After a strange problem with a Word Addin I started from scratch with the MS
example addin. This works a treat on two Win2000 servers.

I also have two Win2k03 servers. If I install it with the "Everyone"
option it duly puts the loadbehavior key in HKLM and works a treat. If I
then log on with a different admin account and run up Word the addin doesn't
run and loadbehavior gets reset to 2. If the second admin account installs
the addin then it works for that account but gets reset when other try it.

All servers are terminal servers and the addin is installed through
Add/Remove Programs. The KB908002 has been installed. The addin was built
with VB.Net 2005. Nothing is appearing in Word's disabled items.

I added some debug lines and I get the following error:

Creating an instance of the COM component with CSSID {...} from the
IClassFactory failed due to the following error: 80010001
