When trying to open a DTS package using SQL Server Management Studio 2005 on Windows 7 (64-bit) get the error:

------------------------------
This package cannot be edited.

SQL Server 2000 DTS Designer components are required to edit DTS packages. Install the special Web download, "SQL Server 2000 DTS Designer Components" to use this feature.

If the "SQL Server 2000 DTS Designer Components" download is already installed, there might be a problem with the compatibility of icons persisted in this DTS package. See the following KB article for more details: http://support.microsoft.com/kb/917406 (Microsoft.SqlServer.DtsObjectExplorerUI)
------------------------------

Opening a DTS Package works on all of our other operating systems including a Windows 2008 R2 64-bit server, Windows 2008 64-bit, Windows XP. I have tried all that I have found suggested online including:

    - Installed SQLServer2005_BC_x64.msi (Backward Compatability).
    - Installed SQLServer2005_DTS.msi.
    - In the PATH Environment Variable have moved 'C:\Program Files (x86)\Microsoft SQL Server\80\Tools\Binn' in front of all other SQL Server folders.
    - Have edited sqlwb.exe.manifest as suggested in http://support.microsoft.com/kb/917406.
    - Have rebooted.
 
All of this to no avail.

Please help.
  
Thanks. John

Actually looks like i now have this working for SSMS 2005 (not SSMS 2008 R2), which may be good enough for now. Below is what I think got it to work. I say I think because it is not completely isolated from other attempts I was trying. Prior to doing this installed SQL 2008 r2 SP1 and made sure SQL 2005 SP4 plus Hotfix was applied the the SQL Tools on this Windows 7 vm machine (meant to only be a client to manage SQL Servers).

1. Uninstall 2005 Backward Compatability and DTS component, if installed.
2. Reboot.
3. Install 2005 Backward compatability.
4. Reboot.
5. Install 2005 DTS Component.
6. Make sure C:\Program Files (x86)\Microsoft SQL Server\80\Tools\Binn\ is before other SQL (100, 90) Binn libraries in the PATH Environment Variable.
7. Reboot

I tried installing the above in various order and this seemed to be the only way that worked with reboots between installs. Hope this helps someone else. Again works for SSMS 2005 not SSMS 2008 R2.
