We installed the 2.5 enterprise platform, then downloaded the 2.12 reference application-add on . when we go to install the installation hangs. The logs reveal the the file is larger than tomcat’s max install limits. none of the methods work for changing that parameter in tomcats files or for open mrs. Also when we try to just load in the omod files that fails and breaks the platform. Please help.

After unzipping the addons, all you need to do is copy and paste them into the modules folder in the application data directory. And then restart tomcat.
