You can try to download winpython: https://github.com/winpython/winpython/releases
It is an executable, but you don't need to execute it as it is a 7zip compressed archive.
You may run it or use directly 7zip to decompress it, the result will be the same. 
 
Then you have a full python installation that don't need to be installed. 
You may try to put your program there and give the users that directory.
