Unable to contact license server

Recommended Posts


I just bought a licence of Malwarebytes Premium and downloaded the application.

When I try to Activate Licence, I type my license key and click on "Activate License", and this error appears:


Then I press OK and this second message appears:


These messages also appear whenever I start Malwarebytes. I've reinstalled, used the cleanup tool, all to no avail.

I really need to get this working.

Thank you for your help.

It looks like you may have used an older version of the Support Tool or something went wrong with it while it was running as your logs appear abnormal.  Please do the following to see if it helps:

  1. Download and run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here

Once that is done, if Malwarebytes still won't activate properly then please do the following (be sure to use the new version of the Support Tool you downloaded from the link provided in my instructions above):

  1. Run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

Please let us know how it goes, and if necessary, provide the new ZIP archive.

Hello again,

I looked deeper at some of the logs you provided and I believe I was able to discover the cause of the issue.  The following entries need to be removed from your HOSTS file as they are preventing Malwarebytes from accessing the licensing server to activate your license key: telemetry.malwarebytes.com keystone.mwbsys.com serius.mwbsys.com keystone.mwbsys.com

Instructions on resetting the HOSTS file to defaults can be found in this Microsoft support article.

Once that is done, try activating Malwarebytes once more to see if it now works and let us know if it was successful or not.

That is alright, we will get the issue fixed.  Please download this file and then extract it and move it to C:\Windows\System32\drivers\etc to replace the file that is already there.

Once that is done, restart your computer and you should be able to activate Malwarebytes with your license key.

Please let us know how it goes.
