Flexicontent does not install on J4 with Gantry5

Hi,
One major database component I use on My J3 website does not provide a roadmap to J4. So I am looking for an other solution.
What I see in documentation flexicontent could be quite promising.
However in documentation I miss the conceptual appraoch based on relational datamodel concepts so I see  a very steep learning curve. But I will figure out somehow.
I got something working on my local host where no other components are installed and I will be testing for data structuers I need.

My goal is to migrate my website from J3 to J4 and reuse the Gantry 5 framework. When I install Flexicontent om my Gantry5 migrated website Flexicontent does not install at all.I get the message :An error has occurred.

1146 Table 'flexi_db.fluve_flexicontent_cats_item_relations' doesn't exist

 There after website cannot be accesed at all.  Looking with myphpadmin in the database I see no flexicontent tables.
This could be a showstopper for flexicontent unless this can be solved.
I don't want to rewrite my basic design. (see www.fluve.nl )
Regards Klaas
