==Java Runtime Environment (JRE) 6 Update 7==
You are encouraged to upgrade for security reasons to Update 7: http://secunia.com/advisories/31010/. This requires the Windows Offline installation package available from Sun. Note that the java Java install package does not replace old versions, so JRE 1.5 and JRE 1.6 can coexist; all older 1.6 update versions (1.6.0 up to 1.6.0 Update 6) are tried to be removed (note that the update version is reflected in the last number in the Uninstall ID).
Notice how the path string in the uninstall check has changed from previous version.
