Addin not getting installed

[Rita]

We have created shared addin for word,excel and powerpoint in C#.
After installing the addin when we open a MS Word application we get an
error message HRESULTS 0 X 80040200 -No such interface found. Because of this
error the MS Word Add-In is not getting loaded properly. However this error
is coming on very few desktops. We need help to identify the root cause of
this problem & possible solution. Same problem comes for powerpoint and excel.

Hi Rita,

Painful waiting for a response on this NG isnt it! From my limited
understanding so far it sounds to me like your AddIn is not registered with
the COM system properly on those desktops where you get the error.
Do you know thew GUID of your AddIn?* If so search the registry for it and
ensure it is found under HKCR\CLSID\yourguid and then check the values of
the inprocserver32 folder and values underneath.
If it looks wrong you could try running RegAsm youraddinname.dll /codebase
on it.

*Your GUID can usually be found in as an attribute on the Connect class in
connect.cs

hi,

Thanks for the response.
I was able to resolve the problem. The problem with those desktop was that
they didn't have stdole.dll and office.dll installed on them and
Microsoft.Office.Interop.Word.dll depends on these dlls . Once these dlls
were installed addin started working fine.
