I have written a VBScript to perform a silent installation of the Sun Java Runtime. Given that I've borrowed SO much from these forums, I figured I should register and give something back. This script installs Java to C:\Program Files\Java. It disables the Java auto-update, disables the creation of the "Java Web Start" shortcut and integrates with Internet Explorer and Firefox. Assumption : You have this version of the JRE and the Microsoft VM uninstaller. You can google unmsjvm.exe and get a copy. Option Explicit Dim oShell, oExec, sCmd, iButton, sProgs Set oShell = WScript.CreateObject("WScript.Shell") sProgs = oShell.ExpandEnvironmentStrings("%ProgramFiles%") iButton = oShell.Popup("Removing Microsoft Java VM",3,"Java Update Tool",0 + 64) sCmd = "unmsjvm.exe /q" Set oExec = oShell.Exec(sCmd) Do While oExec.Status = 0 WScript.Sleep 100 Loop iButton = oShell.Popup("Microsoft Java VM Removed. Now Installing Sun Java VM",3,"Java Update Tool",0 + 64) sCmd = "jre-1_5_0_10-windows-i586-p-s.exe /s ADDLOCAL=jrecore IEXPLORER=1 MOZILLA=1 INSTALLDIR=C:\Progra~1\Java REBOOT=Suppress JAVAUPDATE=0 WEBSTARTICON=0" Set oExec = oShell.Exec(sCmd) Do While oExec.Status = 0 WScript.Sleep 100 Loop iButton = oShell.Popup("Sun Java Runtime Installation Complete.",5,"Java Update Tool",0 + 64) Enjoy!
