句柄"已安装此产品的另一个版本.此版本的安装无法继续..."

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:

已安装此产品的另一个版本.此版本的安装无法继续.要配置或删除此产品的现有版本,请使用"控制面板"上的"添加/删除程序".

如果我在安装产品时运行安装程序,我的32位安装程序可以正常运行我的自定义代码,但是我的64位安装程序中的相同代码和自定义操作无法正常运行并始终显示不需要的错误味精.

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,但包含不同的包.

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.这也基于您的函数名称,即"CheckPreviousVersion".

如果您希望在计算机上找到旧版本时显示自定义消息,请确保首先安装旧版本,但您当前安装了最新版本,但使用的是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，您可以创建一个系统搜索来检查以下注册表项：

HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Microsoft\Windows\CurrentVersion\Uninstall\ YOURPRODUCTCODE

如果此密钥可用，则计算机上安装了旧版本的设置。现在创建一个放置在“CheckPreviousVersion”之前的自定义操作来运行您的代码。将此自定义操作的条件设置为系统搜索中的属性。

这应该够了吧。
