Retain 22.214.171.124 and earlier
Even if the appropriate version of Java is already installed prior to running the Retain installation, the installer still tries to go out to the Internet. If the customer has a proxy preventing Internet access or if the server does not have connection to the Internet for any other reason, this can prevent the installer from completing.
Edit the file, RetainInstall.sh, and find the line JAVA_INSTALLED = "0". Change the "0" to "1" and save.
