The zipped version doesn't require installation and only needs to be extracted
to a folder on your system like:
C:\a-larm

Once extracted, you can add a shortcut to your desktop of file a-larm.exe.

You may want to add a shortcut to the StartUp menu of Windows by dragging and
dropping the a-larm.exe file to this folder:
 * Start -> Programs -> StartUp (Win9x/Me/NT/2K) 
 * Start -> All Programs -> StartUp (WinXP)
