【问题描述】：

我想使用命令行安装最低要求的 .NET，但需要能够检查它是否首先安装这是我将用作登录脚本的当前 bat 文件：

    @echo off

SET FileName=%windir%\Microsoft.NET\Framework\v2.0.50727\CONFIG
IF EXIST %FileName% GOTO AlreadyInstalled

:installingDotnet
@echo Installing Dotnet Now :
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

:Installed
@Echo Dotnet frame v2 Installed

GOTO InstallAtera

:AlreadyInstalled
@Echo Dotnet Framework v2 Already Installed

:Installmyprogram
pause

if EXIST "C:\Program Files\afolder\aprogram" GOTO myprogram
if EXIST "C:\Program Files (x86)\afolder\aprogram" GOTO myprogram

start c:\test\myprogram.exe /Installagent

:myprogramInstalled
@Echo myprogram Installed
pause

:End

但验证文件夹不起作用，我需要验证程序任何帮助 apreciated thx
