BUG: Install Wizard Cannot Distinguish Between MIPS CPUs

When you install a Windows CE Toolkit for Visual Basic 6.0 program created with the Application Install Wizard, certain devices might hang.

This problem has been reported with some devices that use the Phillips PR31700 chipset, and may occur on other devices that use the MIPS 3900 processors. The following devices might be affected:

• Compaq C-Series 810
• Compaq C-Series 2010c
• Philips Velo 1
• Philips Velo 500
• Sharp Mobilon HC-4100
• Sharp Mobilon HC-4500

The CE Services Application Manager and the VBCE Application Install Wizard cannot distinguish between MIPS processor versions. Both the 4000 (1K) and 3000 (4K) options use the line "ProcessorType=4000" to indicate that a program should be downloaded and installed on the device. If the files for the wrong CPU are installed, the device may hang.

Create separate installation programs for each MIPS processor. Add information to your program's installation instructions indicating that the MIPS 3000 (4K) setup should be used for the devices listed above.

If any device hangs during installation, a large .cab file may remain in the \Windows\AppMgr\Install folder. This file should be deleted.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.

Steps to Reproduce Behavior

WARNING: The following steps cause your CE device to hang.

1. Create an installation program for both MIPS processors using the VBCE Application Install Wizard.
2. Install the program on a desktop computer connected to a MIPS 3000 device listed above.

RESULT: The device hangs while trying to decompress the .cab file during installation because the file for the MIPS 4000 was downloaded.
