Before we begin, it's important to understand that there are two types of Pocket PC installation files: (1) those which must be run and installed from your Windows PC (usually .EXE files), and (2) those which must be transferred to your Pocket PC before they can be installed (usually .CAB files).

For installation instructions, select which type of file you have to install:

Install from your pc

Install from your pocket pc

Most Windows Mobile software is installed to your Pocket PC through ActiveSync, the synchronization utility installed on your Windows PC.  Using your pc , download the software you wish to install to your Pocket PC. We recommend downloading to your Windows Desktop so you'll be able to find the file later:

Run the installation file on your PC by double-clicking it on your Windows Desktop.  This should be done while your Pocket PC is synced.

The installation program will install files to your pc 's hard drive, then establish a link with your Pocket PC, copying the needed files to your handheld's onboard memory:

If you have a Windows Mobile 5 handheld, you'll see a pop-up on the Pocket PC's screen to confirm the installation.   Tap "Yes."   If you have a flash memory card installed, a second screen will also appear allowing you to choose the installation destination, internal memory or flash card. Make your choice and tap Install.  Allow the process to complete:

The program is now installed. A soft reset may be required for some software installations.  To run the program, locate it in your Programs menu by tapping Start > Programs.

Some Pocket PC / Windows Mobile software requires that it be installed directly from the Pocket PC. These software setup titles are usually distributed as .CAB files. 

The first step is to move the .CAB installation file you downloaded to the Pocket PC. First, sync your Pocket PC with your Windows PC. After synchronization, select the Explore feature from ActiveSync's main screen.

The Explore feature allows you to browse your Pocket PC's internal storage like you would browse your pc 's hard drive(s) in My pc or Windows Explorer. Once the Mobile Device explorer window is open, go to your Windows Desktop, or wherever the file you want to move to the Pocket PC is stored.  Right-click it. When the menu drops down, select Copy. Return to the Mobile Device explorer window, right-click somewhere in the window, and select Paste:

The .CAB file will be moved to the Pocket PC. Allow this process to complete.  Remove your Pocket PC from its cradle or disconnect it from its sync cable. On your Pocket PC, go to File Explorer in the Program folder on the Start Menu.

Find the file you moved in File Explorer. When you find it, double-click it. It will install itself on your Pocket PC and add itself to the Start Menu or the Programs folder.

You're done.  The program will now appear in the Programs folder:

Once the software has been installed, feel free to delete the .CAB file from your Pocket PC's memory if you wish.
