The OIV installation file includes Java 6. Machines with 32-bit newer versions of Java will not be asked to install version 6, unless the computer has a 64-bit version.
If you have installed and are running OS Sierra version 10.12, you will need to install Legacy Java 6 to launch and use OIV. If you are not alerted to this when opening OIV, you can find the download here: https://support.apple.com/kb/DL1572?locale=en_US
