    • Go to the Account Information: Click on the three dots in the upper-right corner of the screen and go to Account.
    • Check Your Subscription Details: Ensure that your subscription is active, and check the expiration date to confirm that it hasn’t lapsed.
  2. Verify License Key:
    • If you purchased a license key, ensure that the key you entered is correct. A typo or an invalid key can trigger error code MB404104.
    • You can check your Malwarebytes license key by logging into your Malwarebytes Account at https://my.malwarebytes.com and reviewing your subscription details.

Step 2: Restart the Malwarebytes Application

Sometimes, Malwarebytes Error Code MB404104 can occur due to a temporary glitch in the software. In this case, simply restarting the application can resolve the issue.

  1. Close Malwarebytes:
    • Close the Malwarebytes application completely. Ensure it’s not running in the system tray by checking the icons in the taskbar.
  2. Restart Malwarebytes:
    • Reopen the application to see if the error persists.

If restarting the application resolves the issue, it’s possible that the problem was a temporary bug or connectivity issue.

Step 4: Re-enter Your License Key

If you’ve verified your subscription and the error still persists, the next step is to re-enter your license key. An incorrect or outdated key can often cause Malwarebytes Error Code MB404104, so re-entering it may solve the problem.

    • Once you’ve entered the key, confirm the activation process. If your subscription is active, this should resolve the error.

Step 5: Check Your Internet Connection

Since Malwarebytes Error Code MB404104 often involves activation issues, a poor or unstable internet connection could be the culprit. The software may be having trouble connecting to Malwarebytes' activation servers due to a network issue.

  1. Verify Your Connection:
    • Check your internet connection by opening a web browser and trying to visit a website to confirm that you have a stable connection.
  2. Restart Your Router/Modem:
    • If your connection seems slow or unreliable, restart your router or modem. A fresh connection can sometimes solve activation problems.
  3. Disable VPN or Proxy:
    • If you are using a VPN or proxy server, it could be interfering with the activation process. Disable any VPN or proxy temporarily to see if it resolves the issue.

Step 6: Disable Conflicting Security Software

Sometimes, other security software on your computer can interfere with Malwarebytes’ ability to activate correctly. If you have multiple antivirus or firewall programs installed, they may block Malwarebytes from connecting to its activation servers.

  1. Temporarily Disable Other Antivirus Software:
    • If you are using another antivirus program, temporarily disable it and try to activate Malwarebytes again.
  2. Turn Off Windows Firewall:
    • Sometimes, Windows Firewall can block Malwarebytes’ access to its servers. You can temporarily disable the firewall to check if that resolves the issue. To do this:
      • Go to Control Panel > System and Security > Windows Firewall.
      • Select Turn Windows Firewall on or off on the left-hand side.
      • Select Turn off Windows Firewall and click OK.

Remember to turn your firewall and antivirus back on once the activation process is complete.
