Converting Executables

To run Windows CE executables in a Win32 environment (detailed here) you have to convert the executable and related libraries by changing the subsystem number to Win32 GUI

The list of tools to change subsystem

SubsystemTool (recommended)

• Usage:
  • SubsystemTool [path] [subsystem number/name (optional)]
