Question

我的安装程序的32位和64位版本（几乎）具有完全相同的代码和版本。自定义操作序列（只有与此问题无关的细微差别）

我希望我的安装程序检测它是否已经安装过，在这种情况下运行我自己的代码而不是显示默认的Windows Installer错误：

此产品的另一个版本已安装。安装这个版本无法继续。配置或删除现有的如果是本产品的版本，请使用“控制面板”上的“添加/删除程序”。

我的32位安装程序运行完全正常，因为如果我在安装产品时运行安装程序，它运行我的自定义代码，但相同的代码和我的64位安装程序中的自定义操作无法正常工作，并始终显示不需要的错误信息。

CheckPreviousVersion是第一个在UI序列中被称为自定义动作的函数，我尝试将它放在不同的位置，比如在InstallValidate之后，但没有任何作用。

我已经检查了详细的日志文件，但我找不到任何可能解释此行为的内容，这里是日志的一部分：

Answer 1

此消息通常仅在开发阶段出现，而不是在最终用户计算机上出现。出现该消息是因为您只修改了包中的资源并重建它，而不增加版本号，因此Windows Installer发现在计算机上有一个包含相同产品代码和名称的包，但是一个不同的包裹代码。

您的用户永远不会收到此消息，因为我假设您在发布包时会增加版本号。这也取决于您的功能名称，即“CheckPreviousVersion”。

如果您希望在计算机上找到旧版本时出现自定义消息，请确保首先安装旧版本，但您当前安装了最新版本，但使用其他先前构建的软件包（即不同的软件包代码）

Answer 2

如果您使用的是BasicMSI安装程序，则可以创建一个系统搜索来检查以下注册表项：

HKEY_LOCAL_MACHINE \ SOFTWARE \（Wow6432Node）\微软\的Windows \ CurrentVersion \卸载\ YOURPRODUCTCODE

如果此密钥可用，则计算机上会安装旧版本的安装程序。现在创建一个自定义操作，放在“CheckPreviousVersion”之前运行您的代码。通过系统搜索将此自定义操作的条件设置为属性。

这应该可以解决问题。

句柄“已安装此产品的另一个版本。此版本的安装无法继续...”
