Agfeo 4.1.0 and Vista

There is a malfunction when you try to install the new Agfeo-TK-Client 4.1.0 on a Vista machine directly. It doesn't start at all!
You can work around this with the following tasks:
- temporary giving the particular user local admin rights
- install the old 3.*-version of the client
- force a server-side update by starting it and let the server push you the right file
