User Account Control (UAC) is a technology and security infrastructure introduced with Microsoft's Windows Vista and Windows Server 2008 operating systems.
It aims to improve the security of Microsoft Windows by limiting application software to standard user privileges until an administrator authorizes an increase or elevation.
This limitation can create problems to gizmo server when running as a service. It can also introduce problems to Gizmo client, since it requires administrator privileges to perform certain functions.
For this reason we strongly advise you to disable UAC on all computers running Gizmo (Service & client).
Method 2: Manually edit registry
