Mysterious issue with shared COM add-in deployment...

[prilutskiy]

Hi,

I'd like to revisit the issue that was discussed couple months ago
here:
http://groups.google.com/group/micr..."+runtime+error&rnum=2&hl=en#88e4065eb7a4a356

I am trying to deploy a shared add-in for Microsoft Project, created in
Visual Studio 2005. My add-in works fine on several computers that has
installation of Visual Studio 2005. On the other computers I get: Not
loaded. Runtime error occurred during the loading of the COM Add-In.
This is based on 4 positive and 3 negative results.

I simplified my add-in to the "Hello World" level, I granted it with
full trust, I updated the system and Office with all latest updates, I
installed Microsoft patches that were suggested by the author of the
above-mentioned discussion:
http://support.microsoft.com/kb/908002/en-us
http://www.microsoft.com/downloads/...35-C252-43CC-8A2A-6A64D6AC4670&displaylang=en
Latter, actually, was meant for Word and Excel, so it doesn't install
on the box with Microsoft Project only.
..NET 2.0 is installed. I am running out of ideas.

I have two questions:
1. If assume that I am not mistaken about Visual Studio, which makes
the difference, then what does it have, that is required for shared
add-in to load?
2. Is there a way to get more descriptive error message from Microsoft
Project about what happened during loading of the add-in?

Thanks in advance,
Denis.

Hi Denis,

I've recently publish a serie of 9 articles about 'managed' COM add-ins
(with VB.NET 2005)
and I believe the article about troubleshooting may be of first interest:

I figured out that Extensibility.dll was missing on the target system
where Visual Studio was not installed. That caused the problem.

Dennis,

It's a good recource, I'll bookmark it.

Thanks,
