Help! I recommended MBAM Pro 1.51.1800 to a friend (Windows 7 Home Professional) and it is not updating. We are registered. Searched the forums and found that exceptions need to be added for mbam.exe, mbamgui.exe, and mbamservice.exe in the Microsoft Security Essentials settings (Processes) so I did that. I've put a Malwarebytes exclusion in the Windows Firewall. I've also added an "Ignore" for Microsoft Security Essentials in the It still doesn't update at the time I specified. Also, the "Check for Update" button is greyed out EVEN if I run Malwarebytes as Administrator from the right-click menu. (It SHOULD run as Administrator anyway, since there is only one user account on this home computer and it is Administrator. Guest Acct. is disabled.) If I right-click on the Malwarebytes icon in the Taskbar (lower right) and choose "Check for updates" the window opens, it connects to the server, downloads the update and then gives me the PROGRAM_ERROR_UPDATING (5, 0, CreateFile) Access is denied error. This is a problem for me, since I feel responsible for recommending the program and I need to drive out in the country to his house when there is a problem like this. Then doing what I'm supposed to doesn't make a difference. (Running as Administrator does not let me update). Please help. Can I download the latest version and will it still recognize the existing registration or will I have to enter the serial no. again? Maybe the new version fixes the problem??
