Today is holiday in Germany cause of the reunification 1990 of eastern and western Germany. So no business day and I am not in the office.
I decided to play around with some tools and try to install LINQ and BLINQ
Hmm I was quite surprised and have not seen ever before that my machine must be in the domain to install some software.
[UPDATE] As David pointed out. The Setup is looking for "Users" "Power Users" and "Creator Owner" and this fails in my German OS. I manual created it and setup works fine. I am still quite afraid on what's happens next.
