"Allow" button not working when System Software is blocked from loading

I am trying to run VMware and it is being blocked. I go to Security & Privacy and click the allow button next to this message/alert (System software from developer VMware, Inc. was blocked from loading) and the icon shows that it is being clicked but nothing happens and the message/alert remains the same. I tried rebooting my iMac Pro running MacOS High Sierra V 10.13.2 and the message remains and the allow button will not work even when I unlock the changes with my system password.

Any suggestions?

I was able to solve this by quitting the application called MagicPrefs. It was an application monitoring mouse clicks, so Apple was trying to protect the system by not allowing the button to be clicked. It's not a bug with MagicPrefs, and other applications may cause this behaviour too.

FYI, I did a quick write-up on my wiki: http://it.mundy.co/allow_button_not_working_when_system_software_is_blocked_from _loading

Thanks spatchip. I was in the same situation as you and turning off Wifi worked like a charm.
