How to check your Run as administrator option is chosen correctly

To set the Run as Administrator option or to check if you've already set it:

Ensure the GTX program is closed.

Locate the GTX icon that you will click on to start GTX (usually the GTX icon on the Desktop), RIGHT-click it, and select 'Properties'.

In the GTX Properties box, there is a setting you must change: On the 'Shortcut' tab, click the 'Advanced' button.

In the Advanced Properties box that opens, select the 'Run as Administrator' option, then click 'OK'.

Then click  'Apply' and 'OK' to close the Properties box and then Restart GTX.
