¿Qué versión de C++ builder puedo utilizar para un SO de 64 bits?

[CSIE]

Empezado por Laura_C

Me refiero al compilador.Para un SO Windows vista.

O mucho me equivoco, pero si no recuerdo mal C++builder no compila para 64 en ninguna de sus versiones. La XE3 lo incorporará para Noviembre aproximadamente.

Embarcadero dice:

When will a 64-bit compiler be available and how can I get it?

The new 64-bit compiler is coming soon after the XE3 release. There are several options to get the 64-bit support in C++Builder once it becomes available:

Purchase C++Builder XE3 plus Support & Maintenance prior to the release of the 64-bit version and you will get beta access to 64-bit plus any new versions released during the next year. For a limited time you can save 20% on your C++Builder license (new or upgrade) when you purchase it in combination with maintenance.
Purchase RAD Studio XE3 plus Support and Maintenance
Purchase the 64-bit upgrade when it becomes available
