The help says "You can use GetIt Package Manager to discover and install additional third-party software onto RAD Studio." but Indy is not available in GetIt
I dowloaded newest files from Github. I run the Fullc_Rio.bat file then opened Indy260.groupproj but when compiling I got:
[Fatal Error] Cannot compile package 'IndySystem260' which is currently required by Delphi 10.3.
