can't install new version of malwarebytes

[hrwang]

Malwarebytes informs me that a new version of free update is available since yesterday. But it fails install in my PC several times. It firstly tell you to restart the computer shortly after you agree to install, aiming to uninstall the old version. But nothing happens after the computer was restarted. I have malwarebytes premium installed long time ago, and windows 10. It looks like malwarebytes was unable to uninstall the old version during restarting. bugs?

Let's get some Diagnostic logs.

• Create and obtain an mb-check log
  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, then click "OK" 
  3. This will produce one log file on your desktop: mb-check-results.zip
     • 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
• Create and obtain Farbar Recovery Scan Tool (FRST) logs
  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
     • Attach both of these logs to your forum post by clicking on the "Drag files here to attach, or choose files..." or simply drag the files to the attachment area

Hello @hrwang and

Since that update did not go as well as it should have, please consider following this clean install procedure:

1. Please follow the steps in the locked/pinned topic to uninstall the remnants of MB3 and reinstall the latest build: MB-Clean Tool (NOTE: After uninstalling with the MB-Clean tool, you will be asked to reboot.  Once restarted, the tool will ask if you want to re-install Malwarebytes, you can select YES (it will download the MB3 release version) or you can download the MB3 release version manually (currently v3.1.2.1733-1.0.141-1.0.2092) to re-install from HERE).

2. Only if that does not correct the system's issue, then please read the following and only separately attach to your next reply the 3 requested logs - Diagnostic Logs (the 3 logs are: mb-check-results.zip, FRST.txt, and Addition.txt).

Additionally, please consider left-clicking the "Follow" button, near the upper-right corner of your topic, to receive timely email notifications about updates to your topic.

NOTE: The following MB3 information is also available: MB3 User Guide ONLINE, MB3 User Guide PDF, and the MB3 FAQ.

At the end of the above procedure, please reply to your topic with the status of your reported issue.  Thank you.

EDIT: Since my post and the post of @Porthos occurred within a minute of each other, please follow the post above first.  Thank you.
