NSIS如何在安装前结束当前运行的进程

    以前在工作中遇到的一个问题，我们的产品在运行时，点击安装，会报错，找到一个结束进程的控件processwork.dll
    下载地址：http://www.esanu.name/programs/NSISKillProcess.html 
     将processwork.dll放到Plugins目录下，然后在NSIS代码中加入如下函数：

Function CloseParentWithUserApproval
Push $5

loop:
  push "*.exe"
  processwork::existsprocess
  pop $5
  IntCmp $5 0 done

  MessageBox MB_RETRYCANCEL|MB_ICONSTOP “Your process must be closed during this installation.$/r$/n Close your process now, or press Retry to automatically close and continue or press Cancel to cancel the installation entirely.“  IDCANCEL BailOut
  push "*.exe"
  processwork::KillProcess
  Sleep 2000
Goto loop

BailOut:
  Abort

done:
Pop $5
FunctionEnd
