inno setup 安装前判断程序是否在运行

先上图：

安装时候检测：

 

 

卸载的时候检测 

 

 

 

卸载和安装完全🆗了

此外还要下载一个psvince.dll 放在inno setup的目录里

下载地址我上传了：

代码如下

#define MyAppName "My Program"
#define MyAppVersion "1.5"
#define MyAppPublisher "My Company, Inc."
#define MyAppURL "https://www.example.com/"
#define MyAppExeName "MyProg-x64.exe"
#define MyAppAssocName MyAppName + " File"
#define MyAppAssocExt ".myp"
#define MyAppAssocKey StringChange(MyAppAssocName, " ", "") + MyAppAssocExt
