I've put a new version (0.6) of the colorimeter software up on the download site here https://bitbucket.org/iorodeo/colorimeter/downloads/colorimeter-v06.exe
This is an upgrade of the software from Python2 to Python3 and from PyQt4 to PyQt5. It was a pretty big upgrade and there could still be some bugs lurking. If you run into any let me know and I will try to deal with them as quickly as possible. However, supporting the Python2/PyQt4 version of the colorimeter software was starting to get to be too difficult so I really needed to upgrade.
I bundled the python software into a single executable using pyinstaller. The final executable came out kind of large (200MB) which results in a bit of a slow application launch. I'll see if I can reduce the size in the future, but I didn't want this to stand in the way of getting you something to work with.
