@joshuawagner Yeah, sorry about any image naming confusion. We are in the middle of making it easier to know which image you need for the CAP model you own. As such,
RACHEL_Recovery_USB_1-2-16_v9.2.0_20170420.img is zipped as
CAPv1_RACHEL_Recovery_USB_20170420.img.zip to identify it as a CAPv1 image.
@gkholman For future reference, web installs of modules are convenient for 1 or 2. However, if you want to install multiple modules at once, the core modules of a particular language, or you have a list of modules of that you want to install, it's best to follow this wiki page on adding/updating content.
