Norton Anti Virus Gaming Edition 64 bit?

Hi.

 

I currently have a 32 bit system and have pre ordered Windows 7 and intent to install the 64 bit version.

 

I have a current license for NAV GE and obviously it's 32 bit, is it simply a case of downloading a 64 bit version of the software and it'll work with my license key?

 

Also, I have a second PC that will remain 32 bit so is it ok to have a 64 bit version on one PC and a 32 bit on another using the same license?

 

Thanks
