OA 11.20 should be removed completely before installing the older version.
Using oacleanall script should be prefered if there are no Micro Focus products on that machine (using XPL/PerlA package).
In case oacleanall could not be used, removing the OA by oainstall.sh -r -a -clean.
Reinstall the product with 11.14 version, if the product activation fails, do it by: oainstall.sh -c -a -s <mgt. server> -cs <mgt. server>
