I'm trying to associate Python files with a certain version of Python I have installed (I have 2 installed, have just uninstalled a 3rd). Except when I choose the Python executable from the 'Open With' box, it ignores it. As in, completely ignores that I have selected a file as it requested, and just uses the one highlighted in the list instead. So I can't get my Python files to execute with Python now. Wtf? So, I'm annoyed because the programming stuff I intended to do this evening is impossible since I can't run the programs. ANNOYING.

Any suggestions?

Edit: I found a program called Open With Add designed to work around this ridiculous Windows bug. That got me far enough to find out that I can't use the Python installer script anyway, as it tries to download another program and fails. I can download the program manually, but it comes in a certain format, and to install that format you need... an existing installation of that very same program. CRETINS.
