Trouble downloading itunes onto new laptop

Hi guys, I've been trying to download iTunes onto a new HP Pavillion g6 notebook with Windows 7 Home premium.

It never seems to work and the main dialog box I get says

Service 'Apple Mobile Device' failed to start. Verify that you have sufficient privileges to start system services.

Also another dialog box says

Apple Application Support was not found. Error 2 (Windows error 2)

I'm wondering what I need to do now?

Thank you for any help
