So in case you get in touch with a wise installation here are command switches you might need.

/T _ is a Test mode
/X pathname _ will extract all files into pathname
/Z pathname _ will extract all files into pathname and reboots afterwards
/S = quietmode

Uninstall (Unwise.exe switches)

/Z will remove empty directories, including one with unwise itself in it.
/A automatic mode, no user choices other than cancel.
/S silent mode, automatic mode with no user choices
