Malwarebytes install error

Recommended Posts


My malwarebytes auto updated today and it wouldn't start after installing.  I tried uninstalling it but now it would not install again, just says "an error has occurred" and stops installing. 

This is my first time asking question here so if I'm missing some information please let me know.  I attached the mb-check results here, but the checker gave me an error after scanning and I'm not sure if this is the correct report.

I just took a look at your logs and I noticed a couple of things.  First, User Account Control is disabled.  Malwarebytes, like most modern applications, has been designed to be fully UAC compliant and compatible meaning if UAC is disabled it may not be able to install or function properly.  I would strongly advise resetting UAC back to its default settings, both for application compatibility and for the security of your system:

UAC Settings
EnableLUA:                      Off
Consent Prompt Behavior Admin:  Off

Instructions on resetting UAC can be found on this page.  Please try restoring UAC to its default settings, then restart your system and try installing Malwarebytes again.  Hopefully it will work properly now.

Additionally, I noticed that the logs show at least one PUP (Potentially Unwanted Program) installed on the system and there may be others.  I would also recommend following the instructions in this topic and then creating a new topic in our malware removal area by clicking here and one of our malware removal specialists will assist you in checking and cleaning the system of any PUPs and malware threats, and hopefully this will also resolve the issues with getting Malwarebytes installed and running, assuming resetting UAC as suggested above doesn't fix it.  Either way, I would recommend posting in the malware removal area in order to ensure that your system is clear of any threats.

Please let us know how it goes and if there is anything else we might assist you with.

Excellent, I'm glad that it helped.  It could be that the system caught some kind of malware/PUP that disabled it.  I would suggest following the additional instructions above to create a post in our malware removal area just to make sure there are no lingering threats.
