Select button is grayed when on the Notes Pane, trying to select a Notes Data Source.
Also, nmsp.exe /debug:notesaccess shows the following error:
System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E) at Quest.NSP.Transform.NotesQueryEngine.GetUserCanonicalName() at Quest.NSP.Migrator.AccessTest.CanAccessNotes(QueryFactory factory, Options options, Boolean debugAccessFailure)
This error indicates that the Notes DLLs could not be located. This usually means that there is a problem with the Path environment variable. It is possible that the path to the Notes DLLs has not been added to the Path environment variable, or that the Path environment variable has not been formatted correctly. (Sometimes spaces around the semi-colons separating the entries can cause problems).
Please move the path to the Notes DLLs (by default C:\Program Files\lotus\notes) to the beginning of the of the path environment variable. (System Properties->Advanced->E nvironment Variables->System Variables)
Verify if there is no firewall preventing execution of "notes.exe" on the server. Once the restriction is removed the select button is not grayed out anymore.
