Can you reproduce this behavior every time you add a reference to "Microsoft Office Excel"?
Can you please download the latest Ranorex release V2.0.1 and try again?

With version 2.0.1, the exception does not occur.

However after adding the reference, the following error is seen:

Build started.
Build finished successfully. (00:00:01.4329736)
Error loading code-completion information for Excel from Excel:
Could not find assembly file.

You should set a reference to Microsoft.Office.Interop.Excel in the GAC list, as the automatic creation of an office com Interop dll is not possible. This also goes for Microsoft Visual Studio. The Interop assemblies can be installed with the office insulation or downloaded from Microsoft at : http://www.microsoft.com/downloads/deta ... aylang=en.
