what's wrong?

The evaluation is known to have issues with the guest additions. This is what you would expect.

I have friend who have no errors during evaluation.
Something special with my system?

unless you have the exact same hardware, exact same drivers, exact samedisplay configuration, and exact Virtualbox version & guest additions, there is no reason to assume it would work on yours.
