downloading arduino software

I have downloaded Arduino software. When I try to open it I get the Arduino box. It runs through various words and then comes to "starting" My problem is that is as far as it will go. Can someone assist with some ideas as to what may be causing this problem?

Thank you, Eric Hodgson

That might be a Java problem.
If you have Windows 7 or Windows 10, there is no need to install Java. If you have Java installed, try to remove it. Perhaps using JavaRa to remove everything of Java.
In linux a minimal Java should be installed.
