I am planning a Java 7 install across a network of 75 computers. When I ran the script on my test computer, it installed Java 7 properly but Add/Remove programs shows Java 6 is still installed. Should I uninstall Java 6-26?

It does not hurt to leave both installed (in my experience), however, I always uninstall the prior version. If Java does all you need, then uninstall the old version and install the new version. ... Thinkpads_User

My rule of thumb, is keep only what's needed. If you have to remove any, I remove newest to to oldest, and reinstall oldest to newest.

This of course applies to a deployment, or also if your jre is corrupted and you have to remove all versions, and lay down what you need....

You can have any number of java in your system but only one JAVA_HOME environment variable.
you can set Java 7 to JAVA_HOME in system level and let users to override that in user level if they need some older version.

If developers are involved in any of these system. Never remove the older version . Their code may have dependency with specific java versions.
