A user reported the following: "i won some games in i won will not let me play tells me i need to install java I installed java 6 times still unable to play some games ex. pyramid solitaire".

This was reproduced after the user reported it.

Steps followed to reproduce:
1) install 6u31 and go to: http://www.iwon.com/games/card-and-board/pyramid-solitaire.jhtml and successfully play the game.
2) Unistall 6u31
3) Install 7u4
4) Go to http://www.iwon.com/games/card-and-board/pyramid-solitaire.jhtml and try to play the game (Screenshots included as attachment).
5) The site does not recognize that Java 7 is installed.

6) The browser is now directed to a page that has this text"
        "Looks like you need to upgrade to a newer version of Java to enjoy this game"
 
The error caused by the iwon.com site is not specific to Java 7u4. It is all versions of Java 7. Until the iwon.com site is updated, users will continue to see the error.

It is not clear if iwon.com is not detecting Java 7 purposly or on accident. If it is on purpose, they should file a bug against Java 7 and indicate that it is a regression.

Reached out to Mindspark (parent company to iwon.com), by talking to one of the software development team members. Explained to him about the issues with "Pyramid Solitaire". He asked for more details as well as the bug report through email, which has already been sent.
