Hi Francisco,
First of all Creative Cloud ENT is an Enterprise volume serial number so it cannot be registered under retail account.
There is different method for using CCE serial number, install and activating programs.
Please refer the following help article on how to create serialized package for Enterprise customer.

As you have already installed InDesign CC and Creative Cloud Desktop app then next you need to signed out from Creative Cloud first and
create License File using Creative Cloud Packager.

Run this license file on end user machine. it will fix the license issue.
Hope this helps.
