Click above to download, and when the file download dialog box appears, click 'Save' to store the ZIP file on your pc (saving to the desktop is an easy way to go), and close out the Download Complete dialog box.

Next right click the ZIP file and then click on 'Extract All'. Click 'Next', then click 'Next' again, and a new folder entitled 'Word in the World PDA WM' will be created; if you downloaded the ZIP file to your desktop, the folder will be there. Click 'Finish' and a window will pop up showing the folder 'Word in the World'. 

After connecting your PDA to your desktop/laptop computer using ActiveSync, open up windows explorer (right click the Start button and click Explore) and navigate to the 'Program Files' folder on your PDA.

Note: your PDA will show up as 'Mobile Device' beneath all your drive listings and Control Panel. You'll probably have to open a subfolder named 'My Windows Mobile-Based Device' to find 'Program Files' and the correct 'Windows' folder mentioned below.

Copy the 'Word in the World' folder (and all its contents) to the 'Program Files' folder. If it says it needs to convert the files to a different format, click OK.

From Explorer on your desktop/laptop computer, in the 'Mobile Devices' 'Program Files\Word in the World' subfolder, scroll down to the application 'Word in the World.exe' and right click on it, then click 'Create Shortcut'. The shortcut will be created in the same folder at the bottom. Right click it and rename it to 'Word in the World', removing the words 'Shortcut to' and '.exe' at the end.. 

While still in Explorer on your desktop/laptop, navigate to the 'Windows' folder and then to the 'Start Menu'. Note, there may be more than one 'Windows' folder, but only one will have a 'Start Menu' subfolder. Drag (or cut and paste, copy, or move) the shortcut you just created into the 'Start Menu' 'Programs' subfolder. The installation is compete.

To run Word in the World on your PDA, press Start, then Programs, then the Word in the World icon. You can also add Word in the World to the top level of the start menu by going to Settings on the Start Menu.
