What is "delphi-xe2"

On September 1, 2011, Embarcadero released RAD Studio XE2 (codenamed Pulsar), which included Delphi XE2, C++ Builder , Embarcadero Prism XE2 (Version 5.0 later upgraded to XE2.5 Version 5.1) which was rebranded from Delphi Prism and Radphp XE2 (Version 4.0).

Delphi XE2 natively supports 64-bit Windows (except the beginner’s edition), in addition to the long-supported 32-bit versions with some backward compatibility. Applications for 64-bit platforms can be compiled, but not tested or run, on the 32-bit platform. The XE2 IDE cannot debug 64-bit programs on Windows 8 and above.

Delphi XE2 comes with both the VCL and an alternative library called Firemonkey that supports Windows, Mac OS X and Apple iPhone, iPod Touch and iPad portable devices. Firemonkey and VCL are not compatible; one or the other must be used, and older VCL applications cannot use Firemonkey unless user interfaces are recreated with Firemonkey forms and controls.
