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.
that's it.
I've found the hidden jre library in xeams (my os has got the latest but xeams will only use its own).
I forced updated all xeams hidden jre libraries with the ones on my os (latest) and now is working fine.
Cheers!
