Please note that the warning on the first screen shot may not show unless you uninstall and reinstall Universal Control.
When you download Universal Control please run the uninstaller and then restart your computer and then run the installer. Then you need to go to “Settings” —> “Securities & Privacy”
Now, before you click the Allow button, ensure that you "unlock" the page so that you can change these settings.
You will only have 30mins from the time you install Universal Control to give the exception required to install.
