Under Windows, you install Quintus Prolog by running
InstallQuintus3.5.exe. It will prompt for an installation
location (by default C:\Program Files\Quintus Prolog
3.5) and finally give you the option to enter the license
information. If you need to re-enter the license information at a later
time you can run qplm.exe, as described in Running the License Manager.
There is currently no uninstaller for Windows. If, for some reason, you
would like to uninstall Quintus Prolog you can simply remove the
installation folder, e.g. C:\Program Files\Quintus Prolog
3.5.
When using Quintus Prolog from a command prompt you may wish to modify
certain environment variables so that Quintus Prolog components are
found. This can be done by running the qpvars.bat script located
in the Quintus Prolog binaries folder, by default C:\Program
Files\Quintus Prolog 3.5\bin\ix86. Alternatively you can look
at the script to figure out what environment variables it changes and
then perform the same changes using the Windows XP System control
panel.
In addition you may wish to add a shortcut to the qpwin.exe to
the Start menu or desktop. Note that, under Windows, source linked
debugging is only available when running Quintus Prolog with Emacs.
