I would recommend reading through the Evaluation Guide for Windows CE which is linked below. This is a binary OS image that will allow you to evaluate Logic's Windows CE Binary BSP for your application development. In fact many customers have used these images for the first few months of app development before they have hardware available.
The file that you're refering to is the Windows CE Software Development Kit for the LH7A400 card engine. This SDK contains a subset of common Operating System (OS) APIs that allows an application written to the Standard SDK to run on different Windows CE .NET platforms and is for use in Embedded Visual C++ as referenced in the guide above.
Customers that are approved by sales after signing the Binary BSP license agreement and purchasing a bronze support contract ($795) will be given access to Logic's Windows CE Binary BSP.
