如何使用Wix升级必备软件Ms SQL server

我的应用程序需要MS SQL Server作为其先决条件之一。现在，如果客户机有MS SQL Server 2005 express edition，我想将其升级到MS SQL Server 2008 R2 express edition。我无法实施它。以下是当客户端计算机上未安装SQL server时，我用于下载和安装MS SQL server 2008 R2 express edition的Wix代码

您不能使用

/action=INSTALL

参数升级实例，而只能安装新实例。您必须使用

/action=UPGRADE

创建另一个ExePackage，并设置

InstallCondition

，以便根据您执行的注册表搜索选择正确的ExePackage：

   <ExePackage Id="SqlExpress2008R2_UpgradeNamedInstance"
               Cache="no"
               Compressed="no"
               PerMachine="yes"
               Permanent="no"
               Vital="yes"
               InstallCommand="/QS /ACTION=Upgrade /IACCEPTSQLSERVERLICENSETERMS /BROWSERSVCSTARTUPTYPE=Automatic /INSTANCENAME=&quot;[SqlInstance]&quot;"
