Others on a pc and the same version

[he]

We have an addin for vb.net outlook. On our PC
Addin works without problems. It is properly installed and
Start Outlook also loaded and the menu and the toolbar is visible.
At another PC, we have now the problem without the installation
Problems work, but the menu in the Outlook and the Toolbar
.. We have the Service Pack 3, also installed at the same
Surroundings like to have on our PC. Does nothing but ...
What is the reason?
I hope you can help us!

There's no way to tell why the addin is failing on the problem machine from
what you posted. You're going to have to do detective work to see what's
different on the machines where it works and where it doesn't.

Some things to look for are:

Does the addin load and run on the problem machine? Use logging to check
that and also check in the COM Add-Ins dialog to make sure the addin is
enabled and isn't disabled due to load or other errors.

Did your installer check for and if necessary install the Framework, PIA's,
any other requirements or prerequisites such as KB 908002
(http://support.microsoft.com/kb/908002)? Are all dependencies either on the
target machine or installed by you (extensibility, stdole, etc.)?

Does the addin require setting code security in the Framework and if so did
you do that?

Is the code signed if strong naming is required?

Do you have an error log and are any entries in it showing unhandled
exceptions?

Are the same versions of Outlook, whatever you're supporting, on both
machines? Did you develop on and reference the oldest version of Outlook and
Office you're supporting?
