With the sequence of install 7u4 ,fx2.1, jre6u31, then uninstall 7u4, fx2.1. java plugin is not registered with all browswer: FF, IE, GC even though 6u31 is still on the system.

EVALUATION After installing 6u31, the webstart key under 1.6.0_31 is pointed to jre7/bin. which is not correct. This lead to RegisterDeploy() see 1.6.0_31 as an invalid webstart key and ignore there's 6u31 remain on the system. We want to recover this webstart key by detecting JRE on the system.
