Hello

Is there a build in variable or some way my script can tell if you're using a 64 bit software or 32 bit, (and works fine on multilingual windows systems)?

Reason beihing, I need it to to delete a registry entry, but it's on different places on the 64 and 32 bit systems.
I could of course attempt to delete both, but that wouldn't be very neat.

Leo..

Code:

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 := false 
MsgBox % IsWow64Process ? "win64" : "win32"

Thanks to lexikos.
