From sgcWebSockets 2024.3 the Rad Studio IDE for 64 bits is supported when using the automatic installer.
Configuration
There is a new option, "Build Rad Studio IDE Win64," in the setup to allow the installation of components in the new IDE (disabled by default). When this option is selected, the components will be installed in both the 32-bit and 64-bit IDEs. The option is only available for the licenses with source code included.
