Some app you've got, keeps trying to run something, and it needs Java. This is nothing to do with Flash Player.

You can try using Task Manager (Windows) or Activity Monitor (Mac) to see the running tasks when this is happening. Then refuse to install it and see if any tasks have gone away. The list of system tasks will be long and baffling, but I can't suggest anything else.
