Visual Studio 2010 erros when loading expression Editor

[Ben]

Visual Studio 2010 started erroring when loading the expression editor. 

I entered the log information into the devenv.exe.config but did not see any entries in the event viewer.  Should I be looking somewhere else?

Here is the error statistics from the debugger:

System.InvalidCastException was unhandled
  Message=Unable to cast COM object of type 'System.__ComObject' to interface type 'IAssemblyCache'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{E707DCDE-D1CD-11D2-BAB9-00C04F8ECEAE}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Had similar problems with other 3rd party products and only repair of my Visual Studio repair/preinstallation helped (do not remember which one I did)...

[Ben]

Thanks, I'll try a VS repair.  Repairing my Telerik install did not seem to help any.

[Ben]

Unfortunately, neither the VS Repair or the Telerik Reporting repair worked.

[Massimiliano Bassili]

I might have done reinstall of VS, do not remember. Try reporting on another computer, if the same issue, give steps, if not then reinstall VS.

[Nihal]

i have the same problem . have you found any solution for it ?

[Lasse]

I have the same issue - Telerik will you please get into this ASAP?

We are paying big bucks for your products, so any kind of assistance here would be much appreciated!

Resolved the issue by reinstalling Telerik Reporting.
