Appendix 3
Note: This appendix is a quick overview only and has not been comprehensively tested so use with caution. Network uninstalls of a given programme can get bothersome if the target machines aren't all set up exactly the same; say, if you're tidying-up a messy deployment or picking up the pieces after someone else's free-for-all where they handed out root privileges to everyone and their mother like they were liquorice allsorts. If that's the case you're as well to put the whole domain out of its misery and start again. If you do have to keep the domain alive, make sure your uninstall script hasn't any nasty side-effects.
Anyway, if you want to run an unattended command line uninstall of an MSI-installed programme, LibreOffice in this case, you have two options:
Provided you still have it. For LibreOffice, tweak this command to suit your own case:
WshShell.Run "msiexec /qn /x ""\\smuilc\suitalaithe$\libreoffice\original_LibreOffice_installer.msi""", 0, True
If you haven't the MSI file you can try this:
WshShell.Run "msiexec /qn /x {GUID_string_goes_here}", 0, True
A list of uninstall strings for LibreOffice and uninstall strings for LibreOffice help packs can be found at wpkg.org.
More generally, you can find whatever GUID you need by firing-up regedit, drilling down to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall and rummaging around until you find the application to be uninstalled.
