Update of "windows"
Streamtuner2 used to run under Windows. Current versions should still, but aren't tested anymore.
Simplest option to install it is per 0install feed:
(Ought to work for Windows, MacOS, and BSD/Linux systems.)
Else it requires a working Python installation first. That includes Python with Gtk bindings, the requests and pyquery packages.
The available .exe installer is really just a self-extracting ZIP. It'll unpack to Unix-style paths
(The exe is actually more suitable now as raw zip/tarball, that just happens to have a wine GUI.)
With the new .pyz package it's even easier to use however. So that's now the recommended approach. Simply start it with:
Or rename it to have a .pyzw extension, in case your setup already picks that up.
In either case, you'll have to create a desktop shortcut yourself.
Streamtuner2 is primarily developed for BSD/Linux platforms. It's platform-agnostic through Python. On Windows there are enough alternatives already (more bling, mostly just limited in station sources), thus no significant userbase. Which is why this isn't considered a target.
There are probably modern Python distributions for Windows. No idea. It's definitely not something that should be handled on a per-application basis and with PyInstaller embellishments.
