Access Violation - in Delphi 11 UP3 - after installing UNIDAC 10.4

Access Violation - in Delphi 11 UP3 - after installing UNIDAC 10.4

Hello,

after installing the latest UNIDAC version I am getting Access Violations when I try
to install other components. I also have those problems within the RAD Studio when I
click e.g. into the project tree - after de-installing UNIDAC - problems are gone.
