It doesn't allow me to find "open with java"

Hiya, Not massively tech minded here guys so bare with me.. Weeks ago I downloaded and it gave me options open with "blah blah" and I selected Internet explorer because it was literally that or notepad (lol), I then realised maybe it's because I dont have Java? So Today I downloaded it and again the same it tries to open with Internet explorer? How can I get around this

Trial please?
