There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
Upgrade the version of java. The latest version of Xeams no longer works with JRE 1.7. You must use JRE 1.8. Check https://xeams.com/jre.htm for details.
