I successfully installed Delphi (RAD 10.4.2) on my desktop PC. Then attempted to install a couple of extensions to give serial port access. They seemed to crash so I uninstalled them, and the Delphi installation was messed up too, so I uninstalled that. Ever since, the install crashes with a message
Operation error
Cannot load data from the server:
Problem when extracting compressed file.
Thinking perhaps it was running out of space on C: when unpacking files, I have deleted a bunch of stuff from C:, no having about 20G free when starting the install. But I still get the same message. It seems to have installed the basic IDE, but doesn't install the examples, which I very much need as I'm new to Delphi (but not to embedded programming in general (over 4 decades' experience).
My project is stuck until I can install Delphi and get it working. I'm probably missing something very simple, but no idea what it would be. Can anyone help?
