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.
Caleb,
You change the host name at the OS level, not Xeams. However, before you change the name, go to the About screen under Tools and copy the Company Name and Serial Number. You will have to reapply the number once the host name changes.
