Developing and Installing Applications

The 5020 system software automatically associates the CAB file with SETUP.EXE and
installs the application. SETUP.EXE extracts the entire contents of the CAB file into the
\SETUPTMP directory. SETUP.EXE then uses the information in the INF file to copy
files to their destinations, make registry changes, configure the application on the 5020,
store the INF file in the application directory, and store the uninstall information in the
registry.
Note: When you run SETUP.EXE, the contents of the CAB file are preserved. You
can also use /D, /d, /delete, or /DELETE to remove the CAB file as the setup process
progresses.
If the CAB file you are installing is very large or the available space on the 5020 is
limited, you may need to use the /DELETE option. This option reduces the size of the
CAB file as application files are extracted, freeing more program memory.
IMPORTANT! SETUP.EXE writes status messages about the installation to the
SETUP.LOG file. The SETUP.LOG is a text file located in the WINDOWS directory
of the 5020. Errors or problems with the installation are not displayed on the 5020
screen, only the messages in the SETUP.LOG will indicate what has occurred.
Automatic Application Installation
You can automatically install an application during a cold boot by copying an
application CAB file to a compact flash or PC card and inserting the card in the 5020.
To automatically install an application
1. Use CABARC on the host PC to create your application CAB file.
2. Rename the application CAB file OEMINSTALL.CAB.
3. On the host PC, copy the application CAB file to a compact flash or PC card.
4. Insert the storage card in the 5020 and cold boot the device. For more information
on cold booting the 5020, see “Cold Booting the 5020” in Chapter 9.
When the OEMINSTALL.CAB file is found in the Storage Card folder,
SETUP.EXE automatically installs the application from the CAB file. SETUP.EXE
does not delete the CAB file after installation.
Note: Storage Card may refer to the compact flash or the PC card slot, depending on
which card was inserted first. If both slots contain storage cards at cold boot time, the
PC card slot is designated as the Storage Card folder and the compact flash is
designated as Storage Card 2. If the PC card slot contains a radio, Ethernet, or other
I/O card, the internal compact flash card is designated as the Storage Card folder.
