I still use Delphi (remember Borland Delphi/C++ Builder)? It's the same language and IDE, but bought by Embarcadero (they seem to gobble up little technologies here and there).
Anyway, this post is just so I remember that when I install RAD Studio 10.x with the Offline ISO method it breaks the GetIt feature. I don't know why they just don't fix the following and enable it no matter what if you installed online or offline, but here the fix....
At the "C:\Program Files (x86)\Embarcadero\Studio\21.0\bin" command prompt type in "GetItCmd.exe -c=useonline"
It will then successfully re-enable the GetIt functionality.
Adios - `til next time!
