The assembly 'AddinExpress.MSO.2005 is not registered for COM Interop
Error message in VS 2008, but not in VS 2005

Dear support,

I've got the following strange behaviour/error message in VS 2008 and Add-in Express 2008 (v4.2.1908)

The assembly 'AddinExpress.MSO.2005, Version=4.2.1908.2005, Culture=neutral, PublicKeyToken=4416dd98f0861965' is not registered for COM Interop. Please register it with regasm.exe /tlb.

The assembly "C:\Data\At_Home\Projecten\KasteelVanLebbeke\Test2\Test2\bin\Debug\Test2.dll" could not be converted to a type library. Type library exporter encountered an error while processing 'Test2.AddinModule, Test2'. Error: Error loading type library/DLL.

It's easy to simulate on my laptop:
I create a new ADX COM addin, I do not enter any code or reference than the ones automaticaly created. The solution builds fine and the ADX project can be registred. But when I close the solution and I reopen this solution and after rebuild the 2 error messages appear. This is only the behaviour in VS 2008, I've tested in VS 2005 and there it looks OK under the same conditions.

I didn't re-register your assembly as advised under error message 1, because I do not understand why this error appears in VS 2008 and not in VS 2005. I've converted my main project to VS 2008 and it worked for some time. So I must say that I experience this problem only the last days. It did compile before, but now this error message appears in ALL my VS 2008 projects...

Could you please advise?
Thank you!

Hello Nico,

Please try re-installing Add-in Express.

I have a couple of questions for you:

1. Is Visual Studio 2008 up to date? Did you install SP1?
2. What OS do you use? Is it up to date?

Eugene,

I first updated Visual Studio 2008 with SP1 and I thought the problem was away with one of my test projects.
But when I opened my main solution the error messages didn't go away.

So I also re-installed Add-in Express and that fixed it!

I'm now running
1. Microsoft Visual Studio 2008 Version 9.0.30729.1 SP
2. Windows XP Version 5.1 (Build 2600.xpsp_sp3_gdr.080814-1236 : Service Pack 3)

Thank you!
Nico
