This program has only been tested on Windows 10. However, this release was made using PyInstaller, which should make it possible for anyone to use this program whether they have Python or not, and on multiple operating systems.
To use this program, download the .zip file and extract it. Inside the POCoordinateConverter file will be an .exe file. Open that and the program will run, with a Python window running in the background. Don't close it, as it maintains the window that runs the code.
