[Blind-sysadmins] Installing Jaws from an MSI package.

Hello, I am in the process of attempting to role out Jaws 10 to every computer in a domain via group policy. This should be possible however when I obtain the MSI file from the temp directory after the set up file has run, the resulting installation of JFW will not run. It instead complains that a file required for eloq.jls is missing. Can you suggest what may be wrong here? My thinking is that a parameter is passed to the MSI file from the jaws set up executable that instructs it to install a synthesizer component but when the MSI file is run independently outside the set up package it does not install everything required for Eloquents to run correctly. Do any of you have any suggestions? Thanks Darragh
