How to install the extension. 1. In the same folder where the C&C Ancients module is located, create folder for the extension and name it either “C&CAncientsv2_ext” or "C&CAncientsv2.mod_ext", depending on how your system recognizes the module's name. 2. Download the extension file into the extension folder you just created. Do not extract or unzip the extension files or they will not work. 3. Now open the C&C Ancients module (via the “Play Module” button on the Vassal window as normal) and the extension should automatically be loaded with the module, which will be noted in the chat window when the module starts.
