Activate License button greyed out.

Recommended Posts

When I go to the licensing screen to enter my license information, the button to [ACTIVATE] is gray and will not allow me to activate my current license.  Right now I'm running a FREE version of the software, but needless to say I'm frustrated since I have a paid license that I am unable to activate. Im on a mac.

I'm sorry you're having trouble with the software but we should be able to get it to activate properly for you so that you may have the protection you paid for.

First off, you mentioned that you're on a Mac.  Are you running the Mac version of Malwarebytes or are you running Windows on your Mac and are trying to activate the Windows version of the software?

Next, if you are running Windows and attempting to activate the Windows version of Malwarebytes, then please make certain you are logged in as an administrator, as administrative privileges are required to activate the license and protection.  Next, in your administrative user account (assuming that wasn't the issue), go to C:\Program Files\Malwarebytes\Anti-Malware and right-click on mbam.exe and select Properties.  In the properties dialog, click on the Compatibility tab and make certain that all of the boxes shown there are unchecked.  Then click on Show settings for all users and do the same, making certain all the boxes are unchecked, then click Apply and OK, then try launching Malwarebytes again (if it was already open, close it, right-click the Malwarebytes tray icon if it is still running there and select Quit Malwarebytes, then once it is gone, go ahead and launch it again via one of the program's shortcuts).

See if it allows you to activate the software now or not.

If that did not resolve the issue, and you are using Windows then please post the logs requested in the above post beneath where it says technical issues so that we can take a look at the state of the Malwarebytes installation to troubleshoot the issue further.

I see.  Unfortunately I'm not too familiar with the Mac OS version as I have never owned a Mac, however we'll make sure that someone from the Mac team assists you.  I've also asked the moderators to move this topic over to the Malwarebytes for Mac support area to make sure that you get the assistance you need.

If the Activate License button shown in the screenshot below is grayed out after you have entered your key, there are two possible reasons.

One is that you have made a typo and the key was not entered correctly, so it isn't matching the correct form of the key.

The other is that you are entering an old key that is not compatible with Malwarebytes for Mac. Be aware that older keys that include both an ID and a key will not work with Malwarebytes for Mac. This mostly affects lifetime licenses, which are not supported for Mac or Android, only for Windows.
