MMC does not launch in Windows 11 without changing networks

Mike Madrid 0 Reputation points

I have a snap-in for MMC that I use daily. MMC will not launch on my Windows 11 laptop with the snap-in unless I change networks. Here are the steps:

  1. Launch application using MMC (ProjectWise Administrator)
  2. Wait
  3. when application does not launch, I will switch internet connections
    1. switch can be from any network to any network
  4. Application immediately launches when network disconnects and connects to new network.

I have submitted a ticket to the developer of PW Admin and they are looking into the issue and we have tried many things. I have talked to several other people using the same application on Windows 11 and they are not having the issue. I found another post where MMC would not load and followed those steps, but they did not work. These are the steps:

  1. sfc /scannow
  2. delete HKCU\Software\MicroSoft\MMC - this did not actually exist on my computer
  3. reregister all components via the Component Services tool

Any suggestions is greatly appreciated.

    Open a command prompt. Run mmc.exe. From the File menu, select Add/Remove snapin. Select the PW Admin.

    If it hangs at this point, then there is something wrong with that software and you will need to work with their support team to resolve the issue.

    Then do a File/Save as, and save a new .msc file. Try using that.
