Aion Windows 7 RC x64 problem

Hello,
I just installed win 7 rc x64.
I played aion on Windows 7 beta and I copied folder with aion+client install.
On 7 beta everything was ok, I was able to play with no problem.
Now on my new 7 RC x64 I have that error when I trying to run copy of Aion that I took from last 7 system:
[Only registered and activated users can see links. Click Here To Register...]

and that error when I trying to install Aion again:


[Only registered and activated users can see links. Click Here To Register...]

First, if you trying open game without installetion on another windows u have to install directx all updates.
Second, try to install game from windows explorer and with admin privilege.

Problem solved:
I have 2 hard drive in my computer. The problem was that I tryed to instal Aion from drive D. I solved the problem when I copied Aion folder to main system drive C. Now installation was succesfull. :]
