Hi there,

Created a 2003 Office Outlook Add-in using Visual Studio .NET 2005. When
installing the add-in on a non-development machine it appears that the add-in
is not appearing in the Com-Add-ins. I then tried to manually add the
add-in. But when I try to do that I receive the following error message...

<path>.dll is not a valid Office add-in.

Where do I go from now?
 
Have you installed the Visual Studio Tools for Office runtime on the
client machine?

Outlook will not see the dll created by VS as a valid com add-in when
trying to add it manually.
 
Hi Smbolster,

Yes, I have installed VSTO Runtime on the client machine. The only reason
why I tried to manually install it was to see whether it would work. I am
missing something!

I have the SetSecurity solution in my code and have set the required
permission etc.

Any ideas?

Thanks for your reply.
 
Does the client have sp1 or higher?

In help ==> about ==> disabled items is there anything in there?
These will usually show up in the com-addins without a check but you
never know.

Did you add a key in the Add-in project?

Just a few things to look at, other than that I'm not really sure
which way to head.
 
Hi Smbolster,

Yes, the client do have SP1 or higher. Have already checked whether outlook
has disabled the add-in, nothing there. I have entered a key for the
project. The registry loads perfectly on the client machine but the add-in
is just not there. I have checked all possible things..or let's say all
obvious things but now i'm not sure where to look next.

Thanks for your help and advise thus far.

Regards
PJerling
