“No description found” message when editing a maintenance plan in SQL 2005

Here is the fix:

Before you open the management studio, run this to re register the proper DLL’s.

Regsvr32 "C:\WINDOWS\system32\msxml6.dll"
Regsvr32 "C:\WINDOWS\system32\msxml3.dll"
Regsvr32 "C:\WINDOWS\system32\msxml.dll"
regsvr32.exe ole32.dll

Then open the management studio and you will be able to save the changes to your maintenance plan.
