You
can download the .sis file direct to your palmtop via the web
browser. If you already have the Add/Remove control panel you
simply launch it, and use the "Add New" option to install
the .sis file. (Or just double tap the .sis file!) If you don't
have the control panel, download instexe.exe,
and copy it to the machine. Open instexe.exe - it will install
the control panel and then delete itself.
