SYMPTOMS
When you try to start Microsoft Management Console (MMC) with a snap-in on a Microsoft Windows XP-based computer, MMC may not start and you may receive the following error message:

MMC cannot open. This may be because the file does not exist, is not an MMC console, or was created with a later version of MMC. This may also be because you do not have sufficient access rights to the file.

Note In this error message,  is a placeholder for the name of the MMC snap-in file, such as Compmgmt.msc.
