I can help you fix this. However, you will need to tell me two things.
1. Do you have a 64 bit computer?
2. Do you have any version of JDK installed?
3. Do you have 32 bit or 64 bit JDK installed?
Once you give me those three answers I can give you the solution.
Hi there Dinosaur, please read this guide. It should help you get back in game.
