Now, you can create 64-bit Windows applications with Delphi to take advantage of the latest hardware, access more memory, and push the envelope of performance. All Windows technologies are 64-bit enabled including FireMonkey, VCL, RTL, the Delphi compiler and debugger to help streamline the migration of existing VCL applications to 64-bit.
Delphi 64-bit Development Video
Join Embarcadero's David Intersimone as he takes you for a tour of 64-bit development in Delphi including the 64-bit compiler. See how you can take advantage of the benefits of 64-bit and the simple steps to create applications.
Delphi supports the development of 64-bit Windows applications on either a native Win32 development system or a Win64 development system. 64-bit Windows development is available when using VCL and FireMonkey.
