My current Install scripts can detect Win NT. I do not have any more detail that that. I now need to revamp them to detect Vista and have more precise versioning information.

I guess using SYSINFO can give me this information. Does anyone know what values are to be returned when detecting Win 2000, NT, XP and Vista? Do I use GetSystemInfo( WINMAJOR, nvResult, svResult)?

Thanks for your time,

You need to use the system information calls to get both the WINMAJOR & the WINMINOR as those versions of Windows are as follows:

• Windows NT = v4.0
• Windows 2000 = v5.0
• Windows XP = v5.1
• Windows Server 2003 = v5.2
• Windows Vista = v6.0

Hi,

Just to check:
What will be the WINMAJOR & the WINMINOR values for
WinVista 32-bit
WinVista 64-bit
Win2008 32-bit
Win2008 64-bit

As far as I know, Windows Vista & Windows Server 2008 are both identified as v6.0 regardless of their 32/64-bit status.

Similarly, I believe that Windows 7 & Windows Server 2008 R2 are also both identified as v6.1 regardless of their 32/64-bit status.

Hope it helps and certainly feel free to correct me if I am wrong.

Oh by the way, for future reference, I updated the FAQ to include this additional information.

What will be the return values for nvResult and svResult for Win7 64 bit and Win7 32 bit in call GetSystemInfo( WINMAJOR, nvResult, svResult) ?

[Taco Bell]

That call won't distinguish between 32-bit and 64-bit OSes ussmitha, so it would return 6 and "6.1" respectively.

[Perotin]

Maybe you can check for some 64bit-specific system variables, like WINSYSDIR64

btw: Windows 8 should be "6.2"
