I ran JavaRa 2.6 on my Win7 Enterprise x64 PC. It identified the following entries:
Java 7 Update 75 (64-bit) version: 7.0.750
Java(TM) 6 Update 45 (64-bit) version: 6.0.450
Java 7 Update 75 version: 7.0.750
Java(TM) 6 Update 45 version: 6.0.450
However, it missed the following versions (admittedly installed by my company). In “Uninstall or change a program in the control panel, the “Publisher” of each of the below packages is “Oracle”.
Sun JRE 6.0.310
Sun JRE 6.0.330
Sun JRE 6.0.350
Sun JRE 6.0.370
Sun JRE 6.0.390
