“did not work” (I’m assuming you left out a “not”)? In what way?
The one thing often missed, which is mentioned on the J(V)CL GitHub readme’s, is to grab .inc files that are common to both. These don’t come down with a normal git sync, sadly.
The installer adds tabs for each of the versions of Delphi that are installed, but when I ran the install.bat only the first two tabs are visible. Install info tab and Licence tab.
And just looked at what was downloaded from the links on the Project JEDI web site and the two inc files you mention were not in the zip file.
