MB fails to start after 2024-09 Cumulative update for Windows 10 Version 22

[John A]

I get the attached events on startup.

I have left the system as-is.  Who do I PM logs to?

Have you already gathered the following log?

• Download the Malwarebytes Support Tool
• In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
• In the User Account Control pop-up window, click Yes to continue the installation
• Run the MBST Support Tool. The tool also downloads and runs a file called FRSTEnglish. Please allow it to run.
• In the left navigation pane of the Malwarebytes Support Tool, click Advanced
• In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine 
• A zip file named mbst-grab-results.zip will be saved to the Desktop or on the hidden Public desktop (usually C:\Users\Public\Desktop), please upload that file on your next reply

Go ahead and restart the computer and see if Malwarebytes works.

I received the same error on restart

Just a thought, do you have a habit of installing the MS optional untested "preview" updates?

[John A]

No, I read your warning about that in other posts.

I forgot to mention it was KB5043064

Wow, you are just getting that now, lol.

Let's use the same support tool and do a clean uninstall and reinstall.

 

Please close all browsers and programs before running the tool.<<<<< Important.

Once done, it will attempt to reinstall Malwarebytes. After the installation restart the computer.<<<<< Important.

Clean and reinstall fixed it.  I would normally have done this, but I thought I should report it since I had Beta updates enabled.

Thanks for your help.

You did fine. The devs will look at the logs when they get a chance.
