Problems editting SSIS packages (with Visual Studio 2010?)

Hello experts.

SAP BPC 7.5 MS SP11.

I am trying to follow steps in an old guide ("Outlooksoft 5 SSIS Packages") in order to create/modify SSIS packages. 

This document shows how to add the required .dll in SQL 2005:

[...] On top of the Toolbox, right click and select ‘Choose Item’.

After a dialog box comes up:

     - Select ‘SSIS Control Flow Items’ tab.

     - Click ‘Type Names’

     - They will appear sorted by “Type Name”

     - Select all OutlookSoft Tasks listed in image below

          [...]

The problem is that in Visual Studio 2010 there is no 'SSIS Control Flow Items’ tab.

Any idea on how to proceed? How to register the Osoft   .dlls in Visual Studio 2010?

Thanks.
