Windows 7 Vaio Event Service with UAC not work

[Prog]

Hi all,

I have a Sony Vaio notebook. For working Fn and S1 buttons I must have running Vaio Event Service. It works fine but when UAC is disabled. When it's enabled volume control with Fn not work.

Can i do something to work this service with enabled UAC?

Windows 7 build 7000.
