Where can I get the latest ref.chm, I can't seem to find it... Has anyone else tried to use the ProgramFilesDir key in an SP2 install, i.e. can anyone confirm that this is not valid any more? Why would MS change this after so long?!! J. <{POST_SNAPBACK}> Download the deployment tools (link above), and ref.chmn is in the .cab file. To clerifiy, I don't know if it still works or not, I only noted that I couldn't find it in the latest version of ref.chm. Good luck, Chunk
