i typed flarum insallation code. flarum was downloaded to my machine and i tested it on my local host it was sweet.
It seems the flarum part worked pretty good and your issues were with getting composer downloaded and working correctly.
While I wouldn't call that an issue with the flarum installation, it is a component of it.
Unfortunately, windows computers apparently don't seem to have the terminal (command window) to be easily accessible, making composer (a command line interface only program) a difficult thing to run. Especially if you've never run a cli program before!
