COM Interop registration failed

[Alex]

I am writing a Word add-in in C# (VS 2003).

Every once in a while my compiles start failing with the following:

Building satellite assemblies...
Registering project output for COM Interop...
COM Interop registration failed. Access is denied.

If I restart VS, the error disappears for a while then, after several compiles, manifests again.

Any idea what is happening?

Thanks,
Alex.

Hi

I think you may try to use the regmon and filemon to monitor if there is
any access denied when we encounter the issue.

http://www.sysinternals.com/ntw2k/source/regmon.shtml

Based on my experience, it seems that other application is held the tlb
file the VS,NET IDE generated which will be used by the Word to load addin.
Please perform the regmon and filemon to see where the error occurred.

Of course there is an "accsess denied", that was what the compiler complained about!
The error happens on the MyAddin1.tlb file but, according to Process Explorer, the only one who holds it is devenv.exe !

Hi

I am sorry if I did not make it clear.
When we compile the project and try to register for com interop.
In addion to generate the dll and tlb file, the IDE will also need to write
the related register key into registry.
That's why suggest you use both regmon and filemon to see if the only
"access denied" is caused by the face that only the IDE process is holding
the tlb file.

From your reply, we assume now the only access denied is caused by the IDE
held the reference to the tlb file.
If so, I think you may also try to disable all the document view,e.g. *.cs
file and disable all the addin and restart the VS.NET IDE and then try to
rebuild the solution for a few times to see if the problem persists.
If yes, I think we need to do further trouble shooting, can you help to
give a simple reprodcue sample together with detailed reproduce steps so
that we can duplicate the problem at our side to do futher troubleshooting.

I will appreciate your efforts!

Hello Peter,

That is correct.

Sorry, I don't follow you.

and restart the VS.NET IDE and then try to
rebuild the solution for a few times to see if the problem persists.

As I said in the original post, restarting the IDE helps, temporarily.
After several recompiles, the problem happens again.

If yes, I think we need to do further trouble shooting, can you help to
give a simple reprodcue sample together with detailed reproduce steps so
that we can duplicate the problem at our side to do futher troubleshooting.

I don't have a reproducible scenario, it seems sporadic.
Everything works fine, until it doesn't...

Best regards,
Alex.

Since the problem is hard to reproduce, if you do want to find the root

your scenario, we need do dump anaylysis or live debugging which is
