You good ~
I am a beginner, recently doing database, encountered the following problem:
In SQL server 2008 r2 SSMS, SQL server agent under a have homework, to meet an error when you open the job step:

From IClassFactory for clsids for {AA40D1D6 - a56 CAEF - 4 - B9BB - D0D3DC976BA2} the COM components failed to create an instance, the reason is the following mistakes: c001f011, (Microsoft) is essentially) ManagedDTS)

According to the online:
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
(x86)
C: \ Windows \ system32 \ regsvr32 "c: \ Program Files \ Microsoft SQL Server \ 100 \ DTS \ Binn \ DTS DLL"
(x64)
C: \ Windows \ syswow64 \ regsvr32 "c: \ Program Files \ Microsoft SQL Server (x86) \ 100 \ DTS \ Binn \ DTS DLL"

And then restart the MSMS, (Microsoft SQL Server Management Studio)
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
Do not solve the problem, in fact no registrations DLL files, as long as the shut down and the new into the SSMS could open, but will soon appear such problems,
