I have searched high and low for this and found nothing that works for Windows 7 Home Premium 64 bit.
When I try to install some software (.msi) I get the message - "The system administrator has set policies to prevent this installation"
People have found fixes by changing local security policy settings or changing the UAC settings, but none of these work for Windows 7 Home Premium 64 bit.
Just to confirm, I have full administrator privileges!
Is there anyone that can fix this?!
