It's not possible 😉 I don't have problem with install version 7.70. Instalation of version 8.10 work propertly but it don't generate LIB files as it is on 7.70. In “C:UsersPublicDocumentsRAD Studio10.0DCP” I have only two files – “acntBuilderXE3.bpi” and “acntBuilderXE3_R.bpi”, there isn't lib files…
