Tech notes. In a managed computer environment users are restricted, they cannot install programs. Java is a well established program used in a multitude of applications, it is also a widely exploited program and therefore used to compromise computer security. Allowing IT security to manage Java on your computer and running the platform independent or no JRE version is the best compromise between meeting computer security needs and delivering a users ability to use ImagJ and Fiji tools.
