Jorg,
It appears from the first screenshot that you have only have the demo version of the controls installed on your computer. It seems as if you should still be able to select it and click the "Revert" button to make "licensed" if you indeed have a license for these controls. However, in your software summary above, you say that you have Measurement Studio 6.0, which should give you more controls and the version should be 6.0, not 1.0. If you only have Measurement Studio 6.0 you should be using the 6.0 license fixer instead of the 7.0 which is the one referenced in this thread. You can find this utility attached (it can be also be found at http://digital.ni.com/public.nsf/websearch/86256A47004E16D186256A99007BEFB7?OpenDocument which may be temporarily down but will be back up shortly). This utility will find your Measurement Studio 6.0 controls which should be able to be reverted back to licensed copies. If this still doesn't work please repost and we will go from there. I also am unsure what your error message says in English so if you do have further issues, please try to translate error messages into English. Thanks and have a great day.
