Thanks for the reply! I downloaded chibiOS20130208.zip as well as NiRTOS20130201.zip and the FreeRTOS20130208.zip files at the same time so I could try all three. The v1.04 and v1.5.2 installs are fresh default installs. I followed the manual and place the file in the libraries folder and went from there.
is it possible the older codebase was released with a new file name?
