Can't update licensed version

Recommended Posts

Hello and :welcome: :

A couple of easy things to check:
>>First, please be sure your system date/time are correct.

>>Also, please check to be sure there are no "Detected Threats" that need to be dealt with first, as this can prevent the program from updating: Click the "Scan" button at the top of the dashboard and verify that there are no detected threats (especially PUPs or PUMs) awaiting your actions.
>>Then, please be sure that your AV and firewall both give MBAM full permissions. It's possible that your AV or firewall might be treating MBAM as a new program and may be blocking it -- the files that need to be excluded can be found HERE (just the one reply, not the entire thread). Please post back if you need help with that.

If those suggestions don't resolve your issue:

  • Please follow the steps in this pinned topic to uninstall your current version of MBAM and reinstall the latest build - MBAM Clean Removal Process 2x
  • If that does not correct the issue, then please read the following and attach to your next reply the 3 requested logs - Diagnostic Logs (the 3 logs are: FRST.txt, Addition.txt and CheckResults.txt)
  • NOTE: There is an FAQ section with valuable information located here - Common Questions, Issues, and their Solutions

Please let us know how it goes.

Thanks for the reply daledoc,


I've tried the first suggestion for resolving the update issue with MBAM Clean Removal Process, it finally updated,



however, now it doesn't accept my license ID and Key.

In nearly all cases, this is due to inadvertent alphanumeric character substitutions when manually entering the license ID and Key (e.g. "1" and "I", "0" and "O", "5" and "S", etc.)

If you are copying and pasting directly from the confirmation email, be sure not to add any extra spaces before or after the character strings.

The ID should be XXXXX-XXXXX

The Key should be XXXX-XXXX-XXXX-XXXX


See here: It says 'Invalid license information' when I try to activate the software.

See here: How do I activate Malwarebytes Anti-Malware?

If that fails, see here: How do I obtain my license key or confirmation email?


Please let us know how it goes.
