Are all recent laptops and desktops x64 machines ?

Indeed. But that doesn't mean the user runs a x64 OS.
But nowadays new computers tend to come with a x64 OS installed.

Ok I have to check if the installed OS version is a x64 version.

There's a nice Is64BitOS() procedure here http://www.purebasic.fr/english/viewtop ... w64Process
there's also some other "helpful" stuff there.

It depends on your definition of laptops and desktops. Most netbooks and nettops being sold on store shelves have 32bit processors in them.

Most vendors are actually shipping x64 OSs. 32 runs on 64 but 64 doesn't run on 32. 64 just uses a extended instruction set and registers not on old CPUs.

That pretty much sums it up, not exactly a dense subject...no need for riddles

Some do some don't. Here is a list to determine which processors support x64 for Netbooks:

All new core i7,i5,i3,Celerons have x64 support

AMD Semprons do not AFAIK but the rest of their processor lines do.

Do you mind telling us why by the way?

I would hazard a guess that he's writing something in ASM and using the extended operands for 64 bit operations.

Which leaves me curious too on what he is doing

In that case the program wouldn't even compile as a 32-bit application, so the application must be 64-bit, so the os must be 64-bit so he doesn't need to check.

Hi,

I think that netbook's Intel Atom CPUs are 32bit only (at least for the first generation, like N270).
