bat文件來卸載已安裝的應用程序

Question

我正在使用以下bat文件將我的應用程序安裝到用戶計算機上。但是，如果應用程序已安裝，則客戶端希望能夠卸載應用程序，然後安裝新版本的應用程序。

但是，我有2個問題。

1）如何檢測應用程序是否安裝？

2）如果安裝了，我該如何卸載它？

應用程序是一個C＃2005

@ECHO OFF 
:: Copy the configuration file 
copy config.xml "%AppData%\DataLinks.xml" 

:: Search for the CONFIG file, if this doesn't exit then the user doesn't have the .Net framework 2.0 
SET FileName=%windir%\Microsoft.NET\Framework\v2.0.50727\CONFIG 
IF EXIST %FileName% GOTO INSTALL_DIALER 
ECHO.You currently do not have the Microsoft(c) .NET Framework 2.0 installed. 
ECHO.This is required by the setup program for CAT Dialer 
ECHO. 
ECHO.The Microsoft(c) .NET Framework 2.0 will now be installed on you system. 
ECHO.After completion setup will continue to install CAT Dialer on your system. 
ECHO. 
:: Install the .Net framework and then run setup to install the CAT Dialerr 
PAUSE 
ECHO Installing... this could take several minutes...Please wait.... 
START /WAIT NetFx20SP2_x86.exe 
:: If the user cancels the installation of the framework exit batch file 
IF errorlevel 1 GOTO EOF 
Start CATSoftphone.exe 
ECHO ON 
EXIT 

:: .Net framework has been skipped contine to install the dialer. 
:INSTALL_DIALER 
ECHO *** Skiped Dotnet Framework 2.0.50727 *** 
ECHO Installing... Please wait... 
START CATSoftphone.exe 
ECHO ON 
EXIT

<job id="ReInstall"> 
<script language="VBScript"> 
Dim WshShell, oExec 
Set WshShell = CreateObject("WScript.Shell") 
oExec = WshShell.Run("msiexec /uninstall {2E92DD55-37E9-4D6C-B55B-DAFD9DF583E2}" , 1 , true) 
If oExec = 0 OR oExec = 1605 Then 
    oExec = WshShell.Run("InstallUninstallBat.msi") 
End If 
</script> 
</job> 

Answer 1

使用流行的（免費）NSIS安裝程序平臺，而不是使用批處理腳本可能會更好。您可以使用它完成所有相同的事情，並且構建卸載程序要容易得多。

Answer 2

在這裏，在我公司的同一個請求對應一個VB腳本，這是一樣的東西：

<job id="ReInstallblabla"> 
<script language="VBScript"> 
Dim WshShell, oExec 
Set WshShell = CreateObject("WScript.Shell") 
oExec = WshShell.Run("msiexec /uninstall {3D96B234-EB0C-4AC3-89EC-E5CAB9AEC432}" , 1 , true) 
If oExec = 0 OR oExec = 1605 Then 
    oExec = WshShell.Run("blabla_setup.msi") 
End If 
</script> 
</job> 

如果你能夠爲應用程序創建一個部署項目，這都將有一個產品代碼，其您可以將其作爲參數傳遞給msiexec。返回值0表示卸載成功，1605表示沒有找到具有給定ProductCode的安裝。

希望它有幫助。
