Download Java
If the reinforcer doesn’t play (if you’re not sure if they are playing, please click on the “Test Reinforcers” link located below), you may download Java from the following link: https://www.java.com/en/
After you have downloaded the file (take note of where you save the file), you will need to run it for it to be installed.
Remember to retest your reinforcers after you follow this procedure.
