I just upgrade the examples[1][2] to avoid un DOS parser bug:

#v+
IF "%ProgramFiles(x86)%" NEQ "" (
    SET PROG_PATH=%ProgramFiles(x86)%
) else (
    SET PROG_PATH=%ProgramFiles%
)
#v-

The closing paren of %ProgramFiles(x86)% in the SET statement close the
IF bloc, thanks to the DOS parser.

If you need only one variable it can be worked arround like this:

#v+
SET PROG_PATH=%ProgramFiles%
IF "%ProgramFiles(x86)%" NEQ "" SET PROG_PATH=%ProgramFiles(x86)%
#v-

Avoiding the need of paren, if you need more than one variable, you can
use paren and dos function call (or goto if you prefer):

#v+
IF "%ProgramFiles(x86)%" NEQ "" (
    call :64bits
) else (
    call :32bits
)

REM do something with variables

:end
exit /B %ERRORLEVEL%

REM place this at the end of the file to avoid running them again
:32bits
SET SOFT_PATH=HKLM\SOFTWARE\
SET RUN_PATH=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
SET PROG_PATH=%ProgramFiles%
GOTO :EOF
 
:64bits
SET SOFT_PATH=HKLM\Software\Wow6432Node\
SET RUN_PATH=HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Run
SET PROG_PATH=%ProgramFiles(x86)%
GOTO :EOF
#v-

Thanks.
