Some features of the YF client require that you run as administrator. You will only be able to use OpenVPN mode and ECHO connection mode if you run our client application as administrator.

There are two ways to accomplish this.

• Right-click on the link that you use to start our client application, and select "Run as administrator". You'll have to do this every time you start the application.
• Right-click on the link that you use to start our client application, and select "Properties". Go to the "Compatibility" panel and tick "Run as administrator", then apply.

Both methods work with both installer types. For convenience reasons we recommend that you use the second method if you regularly use features that require admin privileges.
