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.
Sergey,
Looks good to me. You MUST be able to restart Xeams from the web interface in order for patching to work. Therefore, after modifying the file and restarting Xeams, try restarting it again from the web interface.
