The C++Builder 64-bit Windows compiler is here. Buy or upgrade to C++Builder or RAD Studio today and you'll also get the 64-bit compiler.

How do I get the C++Builder 64-bit compiler if I don’t have it yet?

Buy any C++Builder XE3 (or later) product or RAD Studio XE3 (or later) product, Professional edition or higher. C++Builder Starter edition is a 32-bit Windows only product and doesn’t include the 64-bit compiler.

How do I get the C++Builder XE3 64-bit compiler if I purchased C++Builder XE3 or RAD Studio XE3 prior to December 10, 2012?

You can download it from the C++Builder or RAD Studio registered users pages at http://cc.embarcadero.com/reg/rad_studio orhttp://cc.embarcadero.com/reg/c_builder. Just be sure to install and register your XE3 product to get access to the update. Look for a notification via email (unless you have opted out of Embarcadero emails), online, or via the “Check for Updates” shortcut in your Windows Start menu under Embarcadero RAD Studio XE3 when the update is available.
