At least it's only an external backup drive. And thanks for your assistance.

Thanks for all the help

MWB support came up with a solution that worked: It is just a guess, but worth checking in this case, please take a look and let me know: Check the environment variables for these entries: DOTNET_GCName=clrgc.dll COMPlus_GCName=clrgc.dll In the Windows search enter sysdm.cpl Select sysdm.cpl from the results In the System Properties window select Advanced -> Environment Variables Look under both User and System for the following entries. If they are present, these are not there by default, please delete them:

Also this message, which indicates a problem with .Net 4.0.30319.0. I have installed SDK 8.0.303 (x64).

Also this message, which indicates a problem with .Net 4.0.30319.0. I have installed SDK 8.0.303 (x64).

In case it is meaningful,the .NET version I installed was MS .Net SDK 8.0.303 (x64). But the error message is saying that it is MWB that has failed, not .NET. Help!

I am now able to watch the Failed start of MWB in the Event Viewer. I am getting the screen below, but have no idea what to do about it! I reinstalled .Net yesterday but it has made no difference. I error seems to be: Failed to create CoreCLR, HRESULT: 0x80004005. I don't know what that means. Any suggestions? Thanks.

Re. Error: (07/13/2024 12:48:07 PM) (Source: disk) (EventID: 11) (User: ) Description: The driver detected a controller error on \Device\Harddisk1\DR1. Search "The driver detected a controller error on \Device\Harddisk1\DR1". It's probably not an issue. See, e.g.: https://answers.microsoft.com/en-us/windows/forum/all/controller-error-on-disk/0fc04d77-b748-4a82-bbdf-858fb83b6d12

Thanks. Personal data is continually backed-up on external drives. Disk1 appears to be one of those external drives (D). Online sources indicate that this is not an unusual error, with a variety of explanations. Your 'solution' sounds pretty radical!! I'll run a disk check on that disk, but how would that affect MWB?

I just re-installed .NET, SHUTDOWN and then STARTED my computer. Ran the Support tool and have uoloaded the new log zip. Thanks for your help. Talk later. mbst-grab-results.zip

Thanks for your prompt response. I turned off Fast startup, restarted the computer, and ran the support tool, and have uploaded the log zip. Logs are uploaded. mbst-grab-results.zip

Ah-hah! Looks like a promising line of enquiry. Note that I think that I had RESTARTED my computer after switching off FAST START. I just SHUT DOWN and then STARTED the computer and re-ran the diagnostic logs program. I have them if needed, but it looks like the error is possibly revealed anyway.

I am running WIndows 11 on a Dell XPX laptop. I noticed a few days ago that Malwarebytes Premium was not running. All attempts to restart it have failed. I've tried running MWB from all available places – desktop, taskbar, start menu, and direct from C:\Program Files\Malwarebytes\Anti-Malware\Malwarebytes.exe. Nothing works. I've checked the services app and Malwarebytes Services is scheduled as 'Running' and 'Automatic'. Malwarebytes no longer appears in the Apps > Startup listing (as it used to). I have run (several times) the MWB Support Tool (latest version) to do a complete clean, followed by a reinstall and reboot. Malwarebytes premium appears to install correctly, but it will not start. After a complete clean, MWB needs to be reactivated. Two other computers on this licence are listed as activated and are running MWB correctly. When I login online and click on "Activate This Device", after trying for some time, I get the message "Device activation failed. Please try again. We were unable to activate your device. Please be sure Malwarebytes is installed and try again." The online activation system is also failing to get MWB running, or is unable to access something it needs in order to do the activation. MWB support have been unable to offer any suggestions other than to do a clean uninstall and reinstall. They have all the logs but have come up with no solutions. Other programs are running successfully. I am now relying on Windows Defender for malware security. I have used MWB on a number of computers for many years and most problems are fixed by a clean uninstall and reinstall, but not this one! What is preventing an installed version of Malwarebytes from running? Informed suggestions please!
