How to check if my pc is 32 bit or 64 bit

[dondie]

Hi i have know read alot of the topics about this, and ppl are saying use @OSArch, or @ProssereArch, but non of them is in my AutoIt? can any one help me with a command, so i can check if my pc is 32 bit or 64 bit? im making a script for my work, where we need to install programmes diffrent if 32 bit then 64 bit.

Best Regards

MsgBox( 64, "Info:", StringFormat("CPU: %s\nOS: %s", @CPUArch, @OSArch ) )

Try:

MsgBox(0, "", "@AutoItVersion: " & AutoItVersion & ", @CPUArch: " & @CPUArch)

Hello donie,

@OSArch is in your AutoIt Helpfile found in helpfile/AutoIt/Macro Reference/System Info Macros.

This example works for me.

Local $cpu_arch_type = @CPUArch
Local $os_arch_type = @OSArch
Local $msgTitle = 'CPU = ' & $cpu_arch_type & ', OS = ' & $os_arch_type 
Select
  Case $cpu_arch_type = 'X86'
    MsgBox( '', $msgTitle, 'Your CPU is 32 bit architecture.' )
  Case $cpu_arch_type = 'X64' And $os_arch_type = 'X86'
    MsgBox( '', $msgTitle, 'Your CPU is 64 bit architecture,' & @CRLF & 'However your OS is only 32 bit architecture' )
  Case $cpu_arch_type = 'X64' And $os_arch_type = 'X64'
    MsgBox( '', $msgTitle, 'Both your CPU and OS is 64 bit architecture.' )
  Case $cpu_arch_type = 'X64' And $os_arch_type = 'IA64'
    MsgBox( '', $msgTitle, 'Both your CPU and OS is 64 bit architecture,' & @CRLF & 'and your OS also supports 32 bit emmulation.' )
EndSelect

Happy Coding!

Edit: Added checks for both architecture types for both CPU and OS. corrected variable name.

i will say thanks to you all, but non of the codes works for me :S

and Realm the path you say Helpfile/Autoit/Marco Reference/System Info Macros only shows me:

@OSLang

@OSType

@OSVersion

@OSBuild

@OSServicePack

and not the @OSArch, and i can not see the @CPUArch.

dondie,

@CPUArch was introduced in the v3.3.0.0 release in Dec 2008 - what version are you running?

MsgBox(0, "Version", @AutoItVersion)

@CPUArch should be the first one on the list.

@OSArch should be the fourth example on the list.

At least they are in my help file.

The example in my previous post is moderately misleading.... I labled the variable as cpu arch as requested from your OP, but was thinking about your request to install the proper versions of software in which you would need the OS to be of the same arch type as well, and the variable $cpu_arch_type... is actually polling the OS architecture type in my example. I apologize for not correcting that when I changed the direction of check, and not explaining why at the same time in my previous post. I will correct that in a moment and add a check for both versions.

i download autoit from the webpage 1 month ago, but weird stuff, i only have version 3.1.1.0 probaly thats why, i will try to redownload autoit and see what happens

[kaesereibe]

x86 = 32bit

AMD64 = x64 = 64bit

$var = RegRead("HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment", "PROCESSOR_ARCHITECTURE")
MsgBox(4096, "PROCESSOR_ARCHITECTURE", $var)

after a re-download of autoit it all works, the problem was that my work have the old 3.1.1.0 version, and that was the version i was using, alle the coeds now working i will say thank you to all of the help and have a good day

dondie,

I suggest you uninstall what you have and the download and reinstal from our webpage - that way you are sure of getting the latest version.

Edit: I see you have done.

you dont need autoit for this..

Simply check the folders on system drive.

64bit systems have Program Files and Program Files(x86), 32bit systems have only Program Files

That's not a reliable check in my opinion.

i know, but im making a auto installing of programmes, that is diffrent from 32 bit and 64 bit, so yes i need autoit to check if the computer is 64 or 32 bit, or else i need to make 2 programms = waste of time

Yes, it is possible to have a 64bit version of Windows without a Program Files (x86) folder. It would be more reliable to check for the existence of the Syswow64 folder.
