the question is in the title, I am not sure how to do it. Help would be greatly appreciated!

>echo %processor_architecture%
AMD64 

Note that this will not work for a script like RunOnceEx.cmd or similar that are called from cmdlines.txt

I mean, this variable is set when the computer makes the first boot after the installation.
Otherwise, try checking if %WinDir%\SysWOW64 exists...

Or you can use AutoIt (@OSArch constant)

I know this is an older post, but here's what I've always used:

%ProgramFiles(x86)%
IF ERRORLEVEL = 1 GOTO x64
IF ERRORLEVEL = 0 GOTO x86

If it exists (ERRORLEVEL = 1), then it runs the 64-bit (x64) commands

If it does not exist (ERRORLEVEL = 0), then it runs the stanard 32-bit (x86) commands.

Of course, you could do the same with SysWow64 instead. Just pick any file or folder that would only exist in a 64-bit OS.

I'd suggest not to use that syntax…
IF ERRORLEVEL = n is first of all not correct
Also an errorlevel of 0 means that errorlevel was 0 or greater which in all cases would be true.

This would probably replace your command better

IF EXIST "%PROGRAMFILES(X86)%" (GOTO 64BIT) ELSE (GOTO 32BIT)

Just for the record.

Errorlevel in NT based systems is a variable:

It's always worked for me, which is why I used it, but I will admit your version is much cleaner and will probably switch to that. By the way, in your version, the ( ) around the GOTO commands doesn't need to be there.

It is wrong, the first line would produce an error every time

'expanded or otherwise variable' is not recognized as an internal or external command, operable program or batch file.

For the next line you could have used among others:
IF ERRORLEVEL 1 GOTO x64
IF %ERRORLEVEL%==1 GOTO x64
IF %ERRORLEVEL% EQU 1 GOTO x64
IF %ERRORLEVEL% GEQ 1 GOTO x64
IF NOT ERRORLEVEL 0 GOTO x64

Are you sure?

Run this code in your console window

IF EXIST "%PROGRAMFILES(X32)%" (ECHO/32BIT) ELSE (ECHO/64BIT)

Result is:

64BIT

Now run this in your console window

IF EXIST "%PROGRAMFILES(X32)%" ECHO/32BIT ELSE ECHO/64BIT

What is the result?
