What version of SQL are you trying to install? What program are you installing that it failed to install SQL?
Did you receive some error on why it won't install?
It's better to have the program itself install SQL as there are hundreds of variations of SQL and how to set it up.
Can we do a remote session to see why the program won't install SQL.

I can't help if you don't reply back to me.
