以下脚本会先找到正在运行的程序和服务，停止并删除服务，然后杀掉正在运行的程序进程

    ;检查服务是否存在
    SimpleSC::ExistsService  "${SVCHOST_EXE_NAME}"
    Pop $0
    ;停止并删除服务
    ${If} $0 == 0

    ;检查主程序是否运行，如果正在运行则进行终止
    nsProcess::_FindProcess "${ANALYST_EXE_NAME}"
    Pop $R0

NSIS打包比较配置文件手动编辑起来非常麻烦，使用HM NIS EDIT向导的话就容易多了。

添加目录以及子目录文件

  File /r "bin\Release\*.*"

删除目录以及子目录

  RMDir /r "$INSTDIR"
