Is there some function to know if the Windows is 32 or 64?
You can use the GetNativeSystemInfo function. Check
TSystemInfo.wProcessorArchitecture = PROCESSOR_ARCHITECTURE_AMD64 to
see if it's 64 bit.
What unit?
I've used this function in Delphi (7) and didn't work:
function is64bitOS: boolean;
var
SysInfo: TSystemInfo;
begin
GetSystemInfo(SysInfo);
Result := (
(Sysinfo.wProcessorArchitecture = PROCESSOR_ARCHITECTURE_AMD64)
or (Sysinfo.wProcessorArchitecture = PROCESSOR_ARCHITECTURE_IA64)
);
end;

Not sure this will work for you or not, but here is what I use:
Program OSType ;
Uses SysUtils;
Begin ;
WriteLn ;
{$IFDEF WIN32}
WriteLn ('This is a 32-bit version of Windows.') ;
{$ENDIF$}
{$IFDEF WIN64}
WriteLn ('This is a 64-bit version of Windows.') ;
{$ENDIF}
End.
The value returned, however, depends on whether the 32-bit compiler of
the 64-bit cross-compiler was used.
