FortiClient 5.6 - administrator rights are required to start forticlient

Hello all,

I've just installed the latest Forticlient via the main forticlient.com webpage. Configured the settings a little - changed webfilter, and antivirus scan schedule. After restarting the computer noticed that Fortclient had not loaded and when I try to start it up manually, it gives me 'administrator rights are required to start forticlient'. I'm logged in as the admin.

Tried to reinstall/uninstall - there is no 'uninstall' button available.

Anyone else have this issue and/or know how to resolve?

Thanks in advance.
