批处理脚本if语句返回错误‘此时意外’

Question

我有一个批处理脚本，它为Win7/WinXP编写注册表项，以便旧的视频游戏可以正常运行，但批处理本身不起作用。脚本如下：

echo on

setlocal ENABLEEXTENSIONS
set KEY_NAME=HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 311080
set VALUE_NAME=InstallLocation
for /F "usebackq tokens=3*" %%A IN (`reg query "%KEY_NAME%" /v "%VALUE_NAME%" 2^>nul ^| find "%VALUE_NAME%"`) do (

set OUTPUT_SEVEN=%%A%%B
)

setlocal ENABLEEXTENSIONS
set KEY_NAME=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 311080
set VALUE_NAME=InstallLocation
for /F "usebackq tokens=3*" %%A IN (`reg query "%KEY_NAME%" /v "%VALUE_NAME%" 2^>nul ^| find "%VALUE_NAME%"`) do (
set OUTPUT_XP=%%A%%B
)

reg query "HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 311080"
if %ERRORLEVEL% EQU 0 goto Win7

reg query "HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 311080"
if %ERRORLEVEL% EQU 1 goto WinXP


:Win7
(
echo Running Windows 7 Script

set QQ=%OUTPUT_SEVEN%
goto exit
)

:WinXP

REG ADD "HKLM\SOFTWARE\Madia\Echelon" /V Path2 /T reg_sz /D %OUTPUT_XP%\\Data\\" /F

set QQ=%OUTPUT_XP%
goto exit
)
:exit
(
start /d"%QQ%" /wait Game.exe
)

在命令提示符下运行脚本：

\Steam\steamapps\common\Echelon was unexpected at this time.

c:\Program Files (x86)\Steam\SteamApps\common\Echelon>set QQ=C:\ProgramFiles (x8
6)\Steam\steamapps\common\Echelon

如果有比我聪明的人能弄清楚这里发生了什么，我会非常感激。

问题在于赋值给变量的值中的圆括号

set QQ=C:\ProgramFiles (x86)\Steam\steamapps\common\Echelon

将被执行。变化

set QQ=%OUTPUT_SEVEN%

转到

set "QQ=%OUTPUT_SEVEN%"

并对其余的set命令执行相同的操作。这可以防止特殊字符出现问题，并避免在存储值的末尾包含不需要的空格。
