If you want virus protection on windows 7 then you need to install SEP 11.0.5

 I have Managed too get 10.2 installed on Windows 7 32-bit OS

But not on Windows 7 64-bit OS

Which Version of Symantec AV is the Supported on Windows 7 64-bit?

SAV can be installed  on Windows 7 but it is not supported

SEP 11 RU5 is supported on Windows 7 ( 32 as well as 64 bit)

 on 64-bit version of windows 7

how would you get it installed?

In CD1 you will have a folder called  savwin64 run the setup from there.
