Hi exitenz and welcome to Windows 7 Forums. First, if you want to know if Java is installed, go to Control Panel, there will be a Java icon there if it is installed. Are you using Windows 7 64 bit, because if you are you need to install Java 32 bit & 64 this might be where the confusion is coming in. If you do have a Java icon in Control Panel, I would just suggest you uninstall it and start over, keeping in mind you need both 32 & 64 bit. Good Luck. Let us know how it turns out.
