Getting the Windows CE uninstaller to work properly

Question

On some of the devices that I am working on, the \Windows directory is not on permanent storage. That is, once the device is rebooted, whatever was written to \Windows is lost. This is particularly problematic for uninstalling programs since wceload.exe (the Windows CE CAB installer program) generates a .unload file and places it in \Windows. The application can be uninstalled before the device is rebooted, but afterward it can't (the "Remove Programs" tool in the control panel comes back with an error about not being able to open the unload file). So how can I get the .unload file to persist across reboots? Is there any way to control where the uninstaller (I believe it is called unload.exe) looks for the .unload file?

Answer 1

I haven't been able to find any good info on this still. It looks like the path to the unload file is hardcoded so the best I can do is make a backup of the unload file. If the user wishes to uninstall they will have to manually copy the file to the \windows directory and then use the uninstall tool in the control panel.
