As Windows 10 (except for a few early releases) is all 64-bit, the instructions for 64-bit builds of previous Windows versions (7/8) should work.

Deep "tech" warning:

Unless you are heavily into programming and/or system configuration, the following guide will probably be too confusing - but for the "tech savvy" it does cover a few optional 'points':

The problem is that the CAW tool does not use the registry values of a Steam installation. It's a minor edit, but one that needs to be made in order to get the tool to work. Also, make sure that if you are working from a Steam install that you are using the version of CAW that works with 1.67 rather than the version that works with 1.69 (Origin's version).

cruinne's guide walks you through the process of making the appropriate registry changes:

You can download the CAW tool here (1.67 is the button on the left):
