How to install C4 on Win 7 64, so I can install C6 upgrade?

Hi guys,

I REALLY am not very good at this kind of thing (computers) at all and I could really use your help! :slight_smile:

I just bought Cubase Studio 4 which came with a Cubase 6 Upgrade. I just installed Cubase Studio 4, but this error message keeps coming up when I go to open the program: "Application ‘Cubase SL 4.0’ has caused the following error:

No protection device connected."

It came with a dongle too and all discs included, but I can’t seem to get beyond this point… can someone please help me out? I’d be very grateful!
