Das ist doch schon mal was. Offenbar schlägt die Installation von
DirectX fehl. Die englischen Release Notes haben dafür was:
Installing DirectX using the GetIt Installer
Zitat:
If you encounter an installation error using the 10.2.3 GetIt based web installer during the
DirectX installation process, we recommend doing the following:
When the "Operation error" occurs, Click "Close". Then, terminate the
IDE.
Double-click the "
RAD Studio 10.2" icon on the Desktop.
