Cannot edit job steps in SSMS 2008 R2

When attempting edit the job step, or view the job step details, I received the following error:

Creating an instance of the COM component with CLSID {AA40D1D6-CAEF-4A56-B9BB-D0D3DC976BA2} from the IClassFactory failed due to the following error: c001f011. (Microsoft.SqlServer.ManagedDTS)

You may also get this error when attempting to create a new job step.

I did a search and found several old post requesting help with the same problem. Microsoft corrected the problem with the last Hotfix; Cumulative Update package 7 for SQL Server 2008 R2.
