Installation 如何检查NSIS中特定端口上运行的进程

我正在使用NSIS为我的应用程序开发一个安装程序。我需要对这个安装程序做的是检查端口80是否可用，如果它可用，请继续安装。如果它不可用，请给出一条错误消息，其中包含在端口80上运行的进程名

我找到了一种检查端口80是否可用的方法。为此，我使用了Ports.nsh作为插件

但是有了它，我就无法在该端口上找到正在运行的进程。我需要给出一个错误消息，例如

//Skype is running on port 80 and close Skype to continue with the installation. 

---

有人能帮我一下吗。谢谢

由于我在nsis中找不到合适的方法来执行此操作，所以我只使用VBScript检查进程名称，并通过nsis脚本调用它。下面是代码

//TestPort80.vbs

Dim WshShell, oExec, key
Set WshShell = CreateObject("WScript.Shell")
Set oExec = WshShell.Exec("netstat -o -n -a")
key = "0.0:80"

Dim values
values = checkPortStatus(oExec, key)
portInUse = values(0)
input = values(1)

If portInUse Then
  x = InStrRev(input, " ")

  ProcessID = Mid(input, x+1)

  commandTxt = "tasklist /FI " & Chr(34) & "PID eq " & ProcessID & Chr(34)

Dim oExec2, key2
Set oExec2 = WshShell.Exec(commandTxt)
key2 = ProcessID

Dim values2
values2 = checkPortStatus(oExec2, key2)
Found = values2(0)
input2 = values2(1)

If Found Then
    y = InStr(input2, " ")
    ExeName = Left(input2, y-1)
        WScript.StdOut.WriteLine "Port 80 is using by " & ExeName
End If
End If
'## If we explicitly set a Success code then we can avoid this.
WScript.Quit 512

Function checkPortStatus(oExec, key)
portInUse = false
input = ""
Do While True

     If Not oExec.StdOut.AtEndOfStream Then
          input = oExec.StdOut.ReadLine()
          If InStr(input, key) <> 0 Then 
        ' Found Port 80
                portInUse = true
                Exit DO
          End If
     Else
        Exit DO
     End If
     WScript.Sleep 100

 WScript.Sleep 100
