Open your Java. For older versions of Windows it should be in your icons bottom right, and for Windows 7 it is in your Control Panel.
Click on Advanced, Java Plug-In. You'll see a checked option named "Enable the next-generation Java plug-in. This is the cause of the problems.
If you can, uncheck it.
If the option is gray and you can't (on Windows 7 64 bits), close the window. Open your Java folder in Program Files, open jre7, open bin, and right click the file javacpl.exe. Click on Properties, Compatibility, and check the option "Run this program as an administrator". This will remove the gray from the option and let you remove the next-generation problem
