Export to excel in TFS 2012, error code: TF400422

Question

I've installed Visual Studio 2012 RC.

I'm working with TFS2012, and when I want to export a user story to excel I get the following dialog box error:

Microsoft Visual Studio
Team Foundation Error
TF400422: Failed to open in Microsoft Excel: Error loading type library/Dll.
(Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY))

I'm using Microsoft Office Professional Plus 2010. Version: 14.0.6112.5000 (64-bit)

Screenshot

What does the TF400422 code mean?

I looked in This page which has a list of error code meanings, but the code: TF400422 isn't there. Perhaps this relates to this other issue.

Answer 1

I'm sorry for the late answer but I was managed to avoid this error by connecting to TFS from Excel using TEAM tab. Then I created new list using TFS Query and it works pretty good

Answer 2

Last I checked the TFS addin didn't work with 64bit of office.

It may have changed since the 2010 version, but it wouldn't surprise me if it was still the case.

Answer 3

The fix for this turns out to be simple - see this blog post for details.

From the registry, when you see two keys under:

HKCR\TypeLib\{00020813-0000-0000-C000-000000000046}\

delete the highest one. In my case this was 1.8, but it will depend on your version of Excel/Office (the artical describes deleting 1.7). This problem does seem to return after some time (maybe after patches), so you may have to re-apply this fix unfortunately.
