I had a problem today with editing maintenance plans in Management Studio 2005 on a server with Windows Server 2003 x64.
The error I get is:
Cannot show the editor for this task.
Additional information:
Exception from HRESULT: 0xC0010014 (Microsoft.SqlServer.DTSRuntimeWrap)
The solution I found was this:
%windir%syswow64regsvr32 “%ProgramFiles(x86)%Microsoft SQL Server90dtsbinndts.dll”
