This registry workshop will help you to fix "MMC could not create the snap-in. The snap-in might not have been installed correctly" in Windows 7 or later.

Microsoft Management Console (MMC) is an inbuilt feature in Windows operating system that lets you to manage snap-in on the go (you can run mmc.exe command to access it). The snap-ins are nothing but a basic component of a console. In the language of set theory, we can say that if a console is a set, then snap-in is its sub-set.

The various snap-ins available in Windows 8 or later editions are Event Viewer, Services, Group Policy Editor, Task Scheduler, Resultant Set of Policy (RSOP), Print Management, Windows Firewall with advance security, Performance Monitor, Device Manager, Disk Management etc.

Sometimes, there may be a possibility of scenario in which some snap-ins may not work properly. Especially, if the registry configuration of a snap-in is broken (note that Registry Editor is not a snap-in), the snap-in initialization would fail. In this case, you’re likely to get following error message (an specific message in case of Event Viewer):

MMC could not create the snap-in. The snap-in might not have been installed correctly.

Name: Event Viewer

CLSID: FX:{b05566ad-fe9c-4363-be05-7a4cbb7cb510}

In our case, the last line of error message is CLSID: FX:{b05566ad-fe9c-4363-be05-7a4cbb7cb510} which helped to us investigate futher about this problem. We started our research by searching this string in Registry Editor. Consequently, we found that issue get resolves with fixing the corresponding registry key for Event Viewer snap-in.

  • Hi Kapil………I have had this problem with Device Manager on a Windows 10 system. This looked like a solution so I made the changes suggested, however when I rebooted and went to check Device Manager, I got the error message “MMC could not create the snap-in.” Is there anything else you can suggest to help me sort this problem out? Thanks.
