最后你可加个目录判断

@echo off
set "s=vc"
set "reg=reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders /f \%s%\ /t REG_SZ"
set "find=findstr/ic:\\%s%\\"
for /f "tokens=*" %%i in ('"%reg%|%find%"') do set str=%%~dpi
if defined str (echo(%str%) else echo,没有安装%s%软件
pause

这个是查找注册表的 不是针对C盘的  既然vc可以 那会不会注册表里路径问题
是路径括号问题
变更下

@echo off
set "s=WFOActives"
set "reg=reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders /f \%s%\ /t REG_SZ"
set "find=findstr/ic:\\%s%\\"
for /f "tokens=*" %%i in ('"%reg%|%find%"') do (
    for /f "tokens=*" %%a in ("%%i\..") do if "%%~nxa" == "%s%" set "str=%%~fa\"
)
if not defined str (echo,没有安装%s%软件)else echo(%str%
pause

@echo off&setlocal enabledelayedexpansion
set "s=V4用户认证"
set "reg=reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Folders"
set "find=findstr/i \\%s%\\.*REG_SZ

)
if not defined str (echo,没有%s%目录)else echo,%str%
