Hi
I installed a new Z3TA, I opened cubase with administrator rights, I entered the registrant code., And like everything is ok but when I open Cubase again but without administrator rights, z3ta2 ask me about the registration code (even though I registered it already) but when opening Cubase with administrator rights Z3TA loads normally and does not ask for the code in again. registrant. 

do I always must open Cubase with administrator rights?  (when I wants to work on z3ta2 )
(I have win7 64bit, cubase 4 32 bit)

Did you ever find your answer? I ran into this problem as well and found how to fix it. Since it has been a while, didn't know if you had fixed this already.

Did you ever find your answer? 

unfortunately not;(

You can write how to deal with that?

Sorry I am so late on this, busy with a remix contest and work =D If you right-click on the Z3TA+ 2 program from the start menu (or find the .exe file), you will get a popup menu. Click on "Properties". Click on the "Compatibility" Tab. At the bottom, there should be a "Privilege Level" heading, under which is an option to "Always Run as Administrator". This should solve your problem.

Thx
