Which “operating system” do I choose? My computer uses Windows 7 but that was not among the choices.
If you are using 32-bit Windows, choose Windows x86
If you are using 64-bit Windows, choose Windows x86_64
How do I know which one I have? There is a little sticker on the computer that says Windows7. there is nothing that says anything about x86 or x86-64.
In your Windows 7, go to Start menu->Control Panel, there choose System and Security, and there choose System. There, you may see System type (32- or 64-bit) right under Memory size.
Thank you. it is 64.
Then choose Windows x86_64
