To install HPlanner on your Palm device:

1.  Depending on your configuration, you might be able to install it just by
    double-clicking the HPlanner.prc file.
2.  If you use Palm Desktop, simply drag-and-drop the HPlanner.prc file onto 
    the Palm Quick Install icon on your desktop.
3.  Alternatively, right-click the HPlanner.prc and select 
    "Sent To | Palm Quick Install". 

This should start the Palm Install tool. If for some reason the HPlanner.prc
file is not yet listed, click the "Add" button, browse to the folder 
containing the .prc file and select it, then click "Open" to add this file to
the list of files to be uploaded to the handheld on the next HotSync.  

HotSync your Palm. HPlanner should be installed now.
