@Will-Dickson, thank you! It works for me on my Windows 10 machine!
I did have some initial connectivity issues, and because my Arduino IDE was old, I uninstalled and reinstalled the latest version of the Arduino IDE to get the latest Windows drivers. The connectivity issues disappeared after that and a reboot.
It even looks looks like you fixed the units issue mentioned in http://forum.iorodeo.com/topic/421/the-colorimeter-app-v4-is-stuck-on-um-but-the-values-returned-look-like-ppm! Thanks.
I'll be happy to provide bug reports for me and the people I'm working with.
I'm also looking forward to having a new v0.6 installer for MacOS, but I appreciate that you prioritized the more pressing Windows issues first.
