I installed Inquisit Lab 6.6.1 on a Windows 7 computer using an administrative account.  I was prompted to register the software which appeared to be successful as shown in the screenshot 

On the same computer I logged on using a different, non-administrative account and was prompted to register the software again.

Is this expected behaviour?  Does every user on the computer have to register the software for themselves?  I assumed the registration was for the computer and not the user.
