ST16 blocked for apps? UAV Toolbox

[OnTheRopes]

I am trying to install UAV toolbox and follow the install procedure, d/l the file and click on it. I then get the message "Install blocked - For security your tablet is set to block installation from unknown sources."
In settings I have unchecked Unknown sources but I still cannot install
Any fixes for this please?

Reboot the tablet after changing the setting. That should solve the problem. If not, also check any anti-virus software settings.
