I have been running Malwarebytes for about 2 years on this machine. The latest update fails to run. The installer starts but when I click Install it pops up a dialog saying the installation failed to start (pleas try running again). I have turned Windows firewall and defender real time protection and no luck. I tried the standalone installer and it failed the same way. I downloaded Hitman pro yesterday and ran a scan. It is in trial mode so I don't see anything it leaves running.
Please let me know what you need as far as logs, etc. to diagnose this problem.
