Target Device

Palm-size PCs running Windows CE version 2.11

Problem Description

Palm-size PC devices running Windows CE version 2.11 hang or reset during the self-registration process of ActiveX controls when they are installed within an Application Installation CAB file. This behavior occurs because the device-install program WCELoad.exe was not invoking CoInitializeEx before the self-registration process.

Update Package Description

This package silently installs the fixed WCELoad.exe file to a connected Palm-size PC device. If the connected device is not a color Palm-size PC, or the device already has the fixed file, then the package exits immediately with a successful return code.

Usage

Your desktop setup program needs to perform the following before invoking CEAppMgr to install the CAB files:

1. Prompt the user to connect the device.
2. Run the WCELupd.exe file and wait for it to complete.
3. Examine the return code and handle it appropriately. In most cases, the only error return code that needs to be handled is the "device disconnected" return code 1.
