我基本上想知道是否有可能从注册表中获取路径并将其用于批处理文件中。
基本上，我所拥有的是从该网站收集的一些代码
@echo off
reg query "HKLM\SOFTWARE\Wow6432Node\Rockstar Games\Grand Theft Auto V" /v "InstallFolder"
该行返回
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Rockstar Games\Grand Theft Auto V
InstallFolder REG_SZ D:\Rockstar Games\Grand Theft Auto V
我在这里要做的就是将GTA的路径添加到批处理文件中，这样我就可以通过批处理文件启动可执行文件（PlayGTAV.exe）。我不使用我已经知道的路径的原因是因为我也希望该批处理文件也可以在某些朋友计算机上工作。
