SQL Server Import and Export Wizard

Yesterday, I was to Upload very large data. So I opened my Sql Server management studio & tried Import/Export wizard. & Surprise !!,

I was not able to start Import/Export wizard.

The SSIS Data Flow Task could not be created. Verify that DTSPipeline.dll is available and registered. The wizard cannot continue and it will terminate.
Cannot create a task with the name "STOCK:PipelineTask". Verify that the name is correct.

I searched the  DTSPipeline.dll  in GAC (Shared Assembly folder). But there are both MSIL & x86 version.
After that I searched Program Files SQL Server folder & found the above dll.

I just registered this dll & my problem has been resolved.

Regsvr32.exe "C:\Program Files\Microsoft SQL Server\90\DTS\Binn\dtspipeline.dll"
Above command will register the required dll.
