How to solve "InstallFailure 'MyUserId' is not a valid short file name" with ANTS Profilers V 10.1

When trying to install or upgrade to Version 10.1(.NET Developer Bundle) I receive the following error message for both the Performance and the Memory Profiler:

MSI returned failure code InstallFailure 'MyUserId' is not a valid short file Name.

How can I solve this issue?

The Installation of the .NET Reflector worked just fine.

    Thanx for the quick reply!

    Sorry, the problem seems to have been caused by a different Plug-In I installed earlier. After running the installation as a different user everything worked just fine.
