FantasyGroundsUpdater: FGUpdaterEngine move failed

[conjoy]

Error above is occurring when I try to update to 3.3.5 on a Windows 10 device.
Have tried fixing windows permissions, any assistance would be appreciated.

Do you use Malwarebytes? Turn it off. Check your other A/V and security programs to see if they are blocking this.

I only had one Anti-Virus and I have just tried uninstalling it, still no joy.
Thanks for the swift responses.

Reboot and try again - the application instance may be still running.

If that doesn't work, download the installer from the main page and try running that. It won't overwrite any of your custom data.
