SSIS Package Load Failure and is missing Execute SQL Task in Toolbox

Question

Also, BIDS closes after right-clicking the toolbox and selecting “Choose Items”.
I’ve tried several ways to fix these issues with no success.
I’m running SSIS/SSMS/SQL Server 2008 R2 (but not running an SQL instance on my PC) on a Windows XP with Service Pack 3 workstation. I get the following errors:
WHEN OPENING BIDS:
I get 2 errors titled “Package Load Failure”. They both reference ‘Visual Studio Explorers and Designers Package’ as being what failed to load. The first message references GUID 8D8529D3-625D-4496-8354-3DAD630ECC1B. The second references GUID AA612177-A69A-4391-B2F4-17F8A88F4BBA
. They both mention contacting the package vendor, but I haven’t got any Add-ins loaded so I’m not sure what that means exactly. They also both ask if I’d like to skip loading the package in the future.
ONCE BIDS IS OPEN:
No error messages appear here. There is no ‘Execute SQL Task’ in the toolbox for Control Flows. Also, if I attempt to open a project containing this object (Execute SQL Task), I get this error in a modal window:
TITLE: Microsoft Visual Studio
There were errors while the package was being loaded.
The package might be corrupted.
See the Error List for details.
BUTTONS:
OK
. . . and these errors in the Error List at the bottom of the IDE:

Finally, when I attempt to add the Execute SQL Task via the Tools menu, “Choose Toolbox Items” selection, I do get the tabbed box for adding things. However, they only come up after issuing this error:
The following assemblies are installed SDK assemblies but could not be shown in the customize toolbox dialog because they are missing one or more components. Please make sure that all necessary libraries are available:
Microsoft.SqlServer.SqlCEDest.dll
Microsoft.SqlServer.Management.CollectorTasks.dll
Microsoft.SqlServer.SQLTask.dll
System.Data.SqlServerCe.dll
Microsoft.Synchronization.Data.SqlServerCe.dll
(above dll repeated at bottom of message)
After this message, I have my choice of .NET Framework Compnents. When I select COM Components, those come up with no problem. The WPF Components tab generates the same dll error above. The Maintenance tab is empty. The SSIS Data Flow Items tab loads fine,
as does the SSIS Control Flow Items tab – but there’s no Execute SQL Task there either.
If you open the toolbox (on a new project, with a project loaded, or without a project loaded) and right-click, then select “Choose Items”, the entire application quickly closes. This “closing behavior” is the same thing you get if you attempt to add toolbox
items through either the Tools menu or the right-click method when you launch BIDS in SafeMode.
In an effort to fix this – I’ve rolled back the .NET Framework version to 3.0 and reinstalled back up to 4; I’ve uninstalled and reinstalled SQL Server 2008 R2 shared services as well as the entire application; I’ve cleared the .tbd files from my user profile;
and I’ve run several things from the command line (devenv.exe /resetuserdata, /setup, /resetskippkgs, etc.). Lastly – I’ve applied every Service Pack and update applicable to my PC (ok, it belongs to my employer – but no one here has been able to figure this
out either).
After having worked this for several days now and, I think, exhausting every available avenue from search engines – I turn to you. Please let me know if you can help. Also, I can provide any additional
files or information you may require.

"You can also go into the folder "C:\Documents and Settings\\Local Settings\Application Data\Microsoft\VisualStudio\9.0" and delete the *.tbd files.  I have had to do this a couple times to get rid of duplicate items and when Reset Toolbox crashes
without warning"
