SQL Server retrieves the method of Enterprise Manager _mssql

Open SQL Server Enterprise Manager, and suddenly a window pops up, which reads:

Error Tip:
The Microsoft Management Console

MMC cannot open file C:Program filesmicrosoft sql Server80toolsbinnsql Server Enterprise manager.msc.

This may be because the file does not exist, is not an MMC console, or is created with a later version of MMC. It may also be because you do not have sufficient permissions to access this file.
Depressed, a minute before the good, how now appear such a situation, can not open Enterprise Manager. Internet Baidu A bit, there are many people like me to encounter this situation. See below for details:

Run MMC, console – Add/Remove Snap-add – Find Microsoft SQL Enterprise Manager – Add – Close – OK (Note: Click here to add after you can close, do not wait for response, if you repeatedly click on the add, then you can see more than n SQL Enterprise Manager ... And then back to the console – Options – Console mode Select "User mode full Access" – Cancels all of the following selections. Finally, save as – from the console – Save as: C:Program FilesMicrosoft SQL Server80toolsbinnsql Server Enterprise Manager.msc (that is, the Binn folder under the installation directory of SQL Server).

If it doesn't work, re-register the DLL
