3. Install the shared version (v4.2.0.82) and follow the steps down here. Follow also the screenshots provided in "ScreenShots WalkThrough" folder for clarification.
>>> REMEMBER >>> don't forget to close the program first and then execute "LicenseMalwareBytes.exe" as admin from CMD!!! >>> VERY IMPPORTANT!!! >>> Just follow the list down here as it is!!!
Steps to follow:
1. Run the installation (Setup .exe file);
2. When finished, open MalwareBytes and go ahead into the "Free" version where you see the "Activate license" button on the upper right near the "Settings" gear icon. Don't do anything and just QUIT MalwareBytes program completely from taskbar;
3. Right click on "LicenseMalwareBytes.exe" and under tab "Compatibility" allow option "Run this program as an Administrator";
4. Run "LicenseMalwareBytes.exe" in command-line (CMD) as Administrator (for more details user can run "LicenseMalwareBytes.exe --help", but you should not need to do anything);
5. Minimize and leave running in the background (DO NOT TRY TO CLOSE the CMD console!!!);
6. Open MalwareBytes, go into its program Settings and in tab "General" scroll down and turn ON "Proxy server" (if you see a popup window appearing with an error message, just ignore it and press "OK" to close the popup window);
7. In the "Proxy server" settings enter the IP = 127.0.0.1 into "Address" and PORT = 9999 into "Port";
8. Now still in MalwareBytes Settings, switch to the tab "Account" to see if the license "Edition" is already activated and marked as <<Premium>> and the "Device name" is resolved with your device name (if you see <<Free>> license, don't panic!!);
9. Return back to the tab "General" and now turn OFF "Proxy server" (the same that you previously turned ON);
10. Return again to the tab "Account" and press "OK" to close the popup window with the error message that will appear (just ignore the message). You should see now the <<Premium>> license for good;
11. Now go to the tab "About" and update the program (but you could also see an automatic popup message from MalwareBytes of new available updates, it is the same);
12. Install the latest MalwareBytes updates when asked after download finishes;
13. Once updated keep trying to update until you get no new updates as some new program updates could come up after a previous one (if you get an error message about no connection just ignore it and try again later);
14. Now you can close the "LicenseMalwareBytes.exe" CMD console and never use it again;
15. Just keep program updates turned ON for future auto-updates;
16. IMPORTANT!!! >> Run a full scan once updated to latest version and ALLOW permanently anything related to the HOSTS file, as if fixed it could remove your hosts entries previously added!! Now you are Done!
4. Enjoy!
