Hi welcome to the forum! It could be that your AV & Firewall needs to be configured,
what are you using, for anAV/Firewall? From the:
Administrators I do apologize for the trouble but in almost every case it has been due to the customers Anti-Virus blocking our new version. The Anti-Malware and Virus field has become much more complicated and those writing the Malware are using more and more sophisticated methods to get onto your box and hide or disable other tools so we, along with the Anti-Virus makers, have had to step up methods to help prevent infections which has also made it more difficult to install other Security Products as well. Though by now these other Anti-Virus vendors know for a fact that we've updated our program and they could very easily do fingerprint analysis of our program and place it within their built-in Trusted Applications list, but many of them do not.
Please review this article and even if you have previously setup or done this method please try again but adapted to your version of Anti-Virus or other Security Tools. Anti-Virus is not the only tool capable of blocking either the program but also updates. Firewalls also automatically block our new version because the fingerprint does not match the previously allowed version, often not alerting because many users either don't enable that feature or they get tired of alerts and turn it off. If you review your other security programs you will probably find deep in the logs where one or more programs are blocking the newer version of MBAM.
Again, please review this post and adapt for your own security software which can be more than just AV blocking.
