Malwarebytes Cannot Start A Scan While Another One Is Already In Progress

When you right click on a file to scan with Malwarebytes you get this message.

What I did to fix this

Made my way to C:\Program Files\Malwarebytes\Anti-Malware\mbam.exe.

Right clicked on mbam.exe, then properties, then compatibility, then ticked run this as administrator.

Rebooted, then right clicked on a file and scanned with Malwarebytes, worked fine.

You probably only need to reboot the PC and all will be good but just in case I changed this to run as administrator.
