Recover License from programs directory

Recommended Posts

Hello everyone, I need some help recovering my license. I lost the access to windows while I was messing up with resizing partitions and now I have an unbootable system that probably cant get fixed. o first of all I don't have my license, (I have bought a lifetime license back to 2010 and I cant find any email any receipt, nothing and of course I haven't connect the license to my malwarebytes account and I never had one) second I haven't deactivate it! Is there any way to make a new malwarebytes installation work by only having the contents of program files malwarebytes directory? And if is possible to recover the license from there, will it work on the same pc with the same operating system in new windows installation since I haven't and I will not have any way to deactivate it from the old installation?


Thanks in advance!!

The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.

Unfortunately your old install from the previous OS will probably not activate/function, however you should still be able to get your license back by creating an account at My.Malwarebytes.com using, if possible, the same email address you used when you originally purchased your license.  Instructions on doing so may be found in this support article.

If that does not resolve the issue then please contact Malwarebytes Support directly as they are the only ones with direct access to license information.  To do so, fill out the web form on this page.

I hope this helps and please let us know if there is anything else we might assist with.

As it seems malwarebytes cares only for the new and "modern" customers that have bought the license from the internet, having accounts and such things!! And the old "traditional" customers that got a license back in 2009-2010 (when buying from internet wasn't so common) and then malwarebytes turned those licenses to lifetime now we a"cold" products for them. Thank you very much for the "great" support malwarebytes and sorry for not being so "modern" buying from the internet, creating account and connecting the license to my account!!


[I have bought the license from the local store and cant find the receipt from 2009 (I have the license inside the computer that can't boot) and I only look for a way to recover it from registry or from program files]

You do not require an account to activate your license; contact Malwarebytes Support as linked above and they will assist you.

As for retrieving your license on the system that won't boot, that likely will not work.  It isn't stored in the registry.  You can try performing a repair install of Windows to get the system to boot again, reinstall Malwarebytes and it may reactivate itself automatically based on the system's UUID, assuming the UUID doesn't change from what it was when the software was activated previously when the OS was still booting before.
