MMC cannot open the file C:/windows/system32/eventvwr.msc

Original title: Network and Share Centre flashes open and then closes again - may be due to MMC.exe![](http://i3.social.answers.microsoft.com/Forums/resources/images/trans.gif?cver=2.13.0068.5)

I am having trouble opening features on Vista which use MMC.  For example, when opening Event viewer, I get an error message "MMC cannot open the file C:/windows/system32/eventvwr.msc" and is then followed by "This may be because the file does not exist,is not an MMC console or was created by a later version of MMC.  This may also be because you do not have sufficient access rights to the file."  Also, I cannot get in Network and Sharing centre - when I click on it, a window opens briefly and then closes.  I have looked on the net and found other have had this problem, but I have not found the solution.  I did once have the system working, so not sure what has changed.  I have tried the sfc.exe and it found no errors.  Can anyone help please???

    Hi JLP42,

    Did you make any changes to your computer very recently before this issue occurred?

    I would suggest you to try the steps mentioned below.

    Method 1: Try registering msxml3.dll

    a.    Click on Start; in the start search type cmd

    b.    Right click on cmd.exe and choose to “Run as administrator”.

    c.    At the prompt that says “C:\Windows\System32”, type the following command and press enter.

               regsvr32 msxml3.dll

    d.    Close the command prompt.

    Restart the computer and check if you’re able to open windows applications or features.

    Method 2: Test the issue by putting the computer into a clean boot state

    A clean boot helps in eliminating software conflicts. Visit the link below to know how to perform a clean boot.

    Note: Once the troubleshooting is over, reset the computer to start as usual.

    Method 3: Provide the event log information

    Hope this information is helpful and let me know if you need any further assistance.

    Remove the cached version of the file from the AppData folder:

    C:\Users\Administrator\AppData\Roaming\Microsoft\MMC
