What I meant was do I also have to instal 32bit??.
If you look at C: / Your going to see Program files and Program files (x86).
The "program files" is your 32 bit programs. The "program files (x86)" are your 64 bit programs.
The sony phone companion should be able to run on a 64 bit OS as im sure all current phone apps are compatible. What specific error message are you getting?
