mmc.exe does not launch msc

Hi, I have a problem on one of my notebooks. I cannot launch an .msc file. If I do so, I do get the mmc.exe in Task Manager, but the mcs (the console with snap-ins) does not show up.

I can start mmc.exe, add snap-ins, save it as a certain .msc, but then I cannot launch that neither by double-click nor bei calling e.g. c:\windows\system32\mmc.exe c:\Users\uname\Desktop\MMC\mmc.msc

It just shows this UAC warning, and then nothing shows up, except I see a mmc.exe process, which I can kill...

I can also just call mmc.exe and then from within, I can open my desired msc, that works.

This only happens on one Windows 11 PC, freshly installed from scratch. Any idea?

thanks,

Dieter

    I’m sorry to hear that you are having trouble with launching the .msc files on your Windows 11 PC. Based on the current web page context, I have found some possible solutions for your issue:

    • One solution is to run the System File Checker tool to scan and repair any corrupted system files. You can do this by opening the Command Prompt as an administrator and typing sfc /scannow and then pressing Enter. This will check the integrity of your system files and fix any problems if possible.
    • Another solution is to reset the Microsoft Management Console settings to their default values. You can do this by deleting the HKCU\Software\Microsoft\MMC registry key using the Registry Editor. To open the Registry Editor, press Windows + R keys, type regedit and then press Enter. Then navigate to the key and delete it. This will remove any customizations you have made to the MMC and restore its default behavior.
    • A third solution is to re-register the Microsoft Management Console components using the Component Services tool. You can do this by opening the Component Services tool from the Start Menu or by typing dcomcnfg in the Run dialog box. Then expand the Component Services node, right-click on My Computer, and select Properties. Then go to the Default Properties tab and click on the Default Authentication Level drop-down menu. Select Connect and then click on OK. This will re-register the MMC components and fix any issues with them.

    I hope these solutions help you resolve your issue. If you need more assistance, please let me know. 😊
