--- Comment #4 from crosstiger crosstieger@gmail.com --- MS Orca is part of the Windows SDK. To avoid downloading the whole SDK I installed the DotNetFramework to get the necessary DLL-Files. Also if you try to install MS Orca without DotNet installed you receives an error that you have to install at least DotNet 2.0.
