Hi,
lets try to explain in short the licensing scheme:
In versions prior to 5.0, we had 3 licenses types, each allowing a different subset of feature to be used:
community, professional, and enterprise.
The "evaluation license" is the same as the enterprise license, but is limited to a 21 days period.
From version 5.0 on-wards, there is just one feature set (i.e. all the features) but we have two licenses types:
commercial and personal according to the where the product is used.
In any case, the product is still available for a 21 days evaluation period.
Hope this clears things
let me know if there are any more questions
