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.
Brian,
PKCS12 definitely works in Xeams. In fact, a certificate from Let's Encrypt uses PKCS12.
If you like, call our support department and we can help you get the PKCS12 cert working.
