Unable to activate program

Recommended Posts


The following entries must be removed from your HOSTS file, otherwise Malwarebytes cannot communicate with the license activation servers and will not be able to activate your Premium license:

Hosts File Blocks
Host data: serius.mwbsys.com
Host data: keystone.mwbsys.com

You will find instructions on resetting the Windows HOSTS file in this Microsoft support article.

Please let us know how it goes and if the issue is now resolved.
