In reply to Olga.

Olga,

Some things are different on Windows 7 -- the location of the Custom tasks folder, for example. Can you verify that you have the proper task DLL in %appdata%\SAS\EnterpriseGuide\\Custom? And that the DLL is Unblocked, per this note?

If you continue to have problems, post back or send me a note at chris.hemedinger[at]sas.com. We might need to turn on some additional logging to see what's happening.
