Uninstall Fortinet Forticlient 6.0

How do I get this program off the computer?  The uninstall button not working??  

Here's how.  (Alternate procedure below)

TESTED in Windows 10

1. Launch FortiClient, then find and select "unlock settings"
   
   
   If successful the "unlock settings" button usually disappears.
2. In the Windows System Tray, right-click the FortiTray icon, then select "Shutdown FortiClient"
   
   
   
3. Once FortiClient is shutdown, uninstall FortiClient using the Windows Add/Remove Programs application.
4. BUT what if the uninstall is not highlighted?!?
   
5. (tested in windows 10 )
   Open a CMD prompt as ADMINISTRATOR 
   
6. Now we'll use the following command.  Please noted that every system I've ever tried this on, the machine force rebooted itself.
   
   wmic product where "name like 'Forti%%'" call uninstall /nointeractive
   
   This command uses the "Windows Management Instrumentation" command line to remove the app.
   
7. It may take a few minutes for this command to run, but generally, if successful, the computer will reboot and the app will be fully removed.

ALTERNATE PROCEEDURE

Are you getting "The specified account already exists"? 

Try this link:
Technical Tip: FortiClient has already been uninstalled, but the error 'A more recent version of FortiClient is already installed' still appears | Community

Open up regedit

backup your registryD

go to HKEY_CLASSES_ROOT\Installer\Products

You'll see a bunch of UUID's listed.  Click in each one until you see the "ProductName" = FortiClient VPN"

DELETE that UUID

Go to %appdata% on your computer

go to %appdata% / local / temp

delete anything in there that is Fortinet in the temp folder.

Now try and uninstall your forticlient and reboot.
