Can't register

Hi
I’ve got a dual boot system,one is windows 7 32bit, the other windows 7 64bit, my daw is on the 32bit system with no internet access, anyway i downloaded the key and it shows as a registry file on the 64bit system but when i load the 32bit system it says key file, and windows don’t recognize it.I put the file in a folder with Schope and when i try it in Sonar 8.52, it’s still unregistered.

Thanks.
Steve.
