Review Manager
Review Manager 5 (RevMan) is the software used for preparing and maintaining Cochrane Reviews. For further info see here http://www.cc-ims.net/
The installer is install4j so you can use -q as the unattended switch. The switch -overwrite is for updating and checks if the files that already exist are the same or older, if they are the same then it skips the install.
