There was a free program I used but it's been years and I can't recall what is
PokerDIY
Note to anyone interested in it:
Most if not all browsers dropped support for the type of plug-in required, you may have to find and install an older ESR version of Firefox to use it.

Firefox ESR v52 (which should work) is still available at https://ftp.mozilla.org/pub/firefox/releases/52.0esr/. Once it's running in the browser, right-click on it to install on the PC. At that point, you no longer need the browser.
