HSO after updating to Cubase 6

Hi,

I set up an environment last year on Windows 7 (32-bit), Cubase 5 and the trial version of HSO. After 90 days I purchased a permanent licence for HSO.

Now I am planning to upgrade my system by going for a Windows 7 (64-bit) system and updating Cubase 5 to 6.

I saw that on the “Cubase 6 Update” DVD there was a trial version of HSO again.

My question:
Should I install the version of HSO that came with my original Cubase 5 and apply the permanent licence to that ?
Or should I install the version of HSO that came with the Cubase 6 Update ? Can my permanent licence be applied to that ?

Thanks, Daniel.
