Extract to C:\Program Files\JavaTM\ (or edit reg file to location of your choice)
TMS must be installed in C:\Program Files\TmSunrise
Java 1.5 is required. You may need to edit the path in the registry file.
If so you will probably be editing it to:
@="\"C:\\Program Files\\Java\\jre1.5.0_02\\bin\\java\" -classpath \"C:\\Program Files\\JavaTM\\jtm.jar\" uk.co.zogger.javatm.Main %1"

add -w if you want the window to stay there once it's downloaded.
