AutoHotkey Community

Hello, y'all! I have to provision over 100 computers, so I wrote an AutHotkey_L script to help me.

I need to use the same script on each computer, and some of them are 32bit Windows7 and some are 64bit Windows7, so I put both 32bit and 64bit AutoHotkey_L in my launching folder (I launch over a LAN network).

Now, I found this function in these forums to tell if I am using a 64bit computer or not. Problem is this:
32bit system + 32bit ahk = false
64bit system + 32bit ahk = true

64bit system + 64bit ahk = false !!!!

Any clues?


is64bit(){
ThisProcess := DllCall("GetCurrentProcess")
; If IsWow64Process() fails or can not be found, assume this process is not running under wow64.
; Otherwise, use the value returned in IsWow64Process.
if !DllCall("IsWow64Process", "uint", ThisProcess, "int*", IsWow64Process)
IsWow64Process := 1
;MsgBox % IsWow64Process ? "win64" : "win32"
return %IsWow64Process%
}

This should give you either "32-bit" or "64-bit", depending on the version of Windows installed (but I can't test it on 64-bit):

Thank you. That, however, will work on the 64bit machine with autohotkey_L both 32 and 64 bit versions, but it won't work on my 32bit machine with 32bit ahk_L. I need this to work on both architectures with both versions.

Take a look in this:


Pretty much, Im checking the A_ProgramFiles variable to see if it contains the x86 portion, which would indicate that it is on a 64 bit os. Not sure if that is going to work 100% of the time, but its worth a shot.

Some of the code I write will not work without it.

Hello! I actually thought of doing that, but rejected it for a more viable method. Maybe I'll just go back to that method. I haven't encountered a situation where someone would have a x86 Program Files in their 32 bit system yet! Thanks for the reminder, and the snippet.

I tried out your snippet, however that only works if autohotkey is inside of a program files directory. With that all being said, I think this is better:


whatitis := is64bit()
MsgBox % whatitis ? "win64" : "win32" ;%

;See whether the computer is a 64bit operating system or not
;return 1 or 0
is64bit(){
ifexist, C:\Program Files (x86)
{
b = 1
}else{
b = 0
}
return b
}

Shorter version:

Funny thing, A_OSType always gives me WIN32_NT but I know for a fact it is 64bit Windows 7. a_ptrsize is even 8, while on my 32 bit system, I also get WIN32_NT with a pointer size of 4. Strange or I don't understand something!

Where do you get: OSArchitecture ? That gives me an error.

I changed it to return a Boolean value. Refresh page

Sorry, I should've realized that. That is shorter (nicer!) Thanks!

The easest way I found is this:



In 64 bit AHK L A_PtrSize is 8, in 32 bit AHK_L it is 4 and in AHK Basic it is blank.

Ha! That is even better! AND it is more viable! Great! Thanks!

A word of warning: A_PtrSize will tell you the "bitness" of the EXE which is running the script, not the "bitness" of the OS. If the EXE is 64-bit, so is the OS (at least, until a hypothetical >64-bit Windows OS comes out), but the reverse does not hold true.
Win32 does not mean 32-bit Windows.

Yes, I just noticed that. a_ptrsize gave me the wrong value when I used in 32bit ahk.

Thanks for the tidbit about win32; I was suspecting that.
