[ RESOLVED ] Can not activate my Malwarebytes Premium

Recommended Posts

Hi !
I recently had to uninstall my MB Premium due to some computer problems. Upon trying to reinstall it I have now encountered the problem that I cannot activate my MB Premium installation.
Have tried to....
  1. Download/install from my MB web account + used the web based "ACTIVATE" function, but it does not work (see attached screenshots).
  2. Use the download link e-mailed to me after completing my payment (which also includes a ID + Key), but get a failure message when trying (see screenshots).
  3. Have installed and run the MBClean tool + tried to clean out all previous traces of an earlier MB installations using REVO Uninstall tool (Deep Clean), and then tried to install again from both my web account and the e-mailed download link, but the problem remains as before.
For your support to analyze the issue, I followed all the steps in the suggestions provided in a MB forum where it was suggested as follows:

@nunaka I am sorry to hear you are having issues with our product. Sounds like we need to dive deeper into this to find out what's going on. In order to do that, we will need some logs from you.

Please run these two tools and then attach the logs in your next reply:

NOTE: The tools and the information obtained is safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  • Farbar Recovery Scan Tool (FRST)
    1. Download FRST and save it to your desktop
      Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit
    2. Double-click to run FRST and when the tool opens click "Yes" to the disclaimer
    3. Press the "Scan" button
    4. This will produce two files in the same location (directory) as FRST: FRST.txt and Addition.txt
      • Leave the log files in the current location, they will be automatically collected by mb-check once you complete the next set of instructions
  1. Download MB-Check and save to your desktop
  2. Double-click to run MB-Check and within a few second the command window will open, press "Enter" to accept the EULA then click "OK" 
This will produce one log file on your desktop: mb-check-results.zip
  • This file will include the FRST logs generated from the previous set of instructions
  • Attach this file to your forum post by clicking on the "Drag files here to attach, or choose files..." or simply drag the file to the attachment area

Hi !

Thanks a lot for the suggestion. However, what was suggested (in the link) it did not apply to my situation as I had already uninstalled MB for the computer that I cannot activate my Premium license for. In other words, the device was no longer visible on my account page.

However, when I went to Settings in my installed free version of MB, it was an option for "Activate" there. Clicked it, and then it worked. Fantastic (finally)!

A bit strange that it worked from Settings in the free version (after adding my e-mail address + password), but NOT so when I tried to click on Activate - and added my e-mail address + password....as instructed - on the free version's main interface. Nor when logging into to my account and clicking the option Install + Activate on "This Computer".

Anyway, now it works...

Again, thanks a lot for your support !

Cheers !
