I have had MB3/Win 10 64 bit, installed and running on my Asus g73jh since November, no problems until last Saturday (1-27). I had a Windows 10 freeze up. It took a couple RESTORE attempts and 5 or 6 reboots/shutdowns to stabilize the system. In the meantime, Malwarebytes 3 suddenly became inaccessible, no matter how I approached it. Desktop icon/tray icon didn't respond, going into Programs and launching there --- nope. Windows Defender showed that attention was needed regarding MB3.
After scouring the forums, I finally decided to try an Uninstall-Install. Now I cannot download and reinstall MB3 at all, even after running MB Clean. Every time I tried opening "mb3-setup-consumer-x.x.x.xxxx.exe after, however, each time I receive the error message "ShellExecuteEx failed; Code 2147746132. Class not registered."
I was able to unzip an Windows-mb-installer and get it to run....for a few seconds before I got this error message:
Class not registered, ClassID
I am about at the point where I say screw it and reformat with clean install of Windows and piece together the apps, like Civ V, GoPanda2, etc. Do you have any suggested fixes that I haven't tried. I am in no way a power user. Thanks.
