Question

我收到错误＆＃34; system.deployment.application.deploymentdownloadexception（未知子类型），无法下载应用程序。应用程序缺少必需的文件＆＃34;在我的win c＃apllication（visual studio 2012）中，当我尝试为我的clickonce应用程序运行setup.exe时。

在设置安装文件夹（共享文件夹）并在网络共享中发布（使用visualstudio向导）后，我进行了Clickonce部署。

在Visual Studio中的

我在我的网络文件夹中设置安装文件夹URL： \ srv \ Deploy \与Visual Studio向导中的相同位置，用于发布此应用程序以及用户将如何安装应用程序（来自UNC路径或文件共享）

在visual studio向导之后，自动生成部署网页，我点击安装按钮（下载setup.exe）来安装我的应用程序。 setup.exe在C：\ Users \ Gio \ Downloads中下载当我点击setup.exe时会产生错误：

system.deployment.application.deploymentdownloadexception（未知子类型）

我尝试在默认网站中添加mime类型（.config，.manifestapplication），但错误以同样的方式出现

如果我从我的网络文件夹\ srv \ Deploy \运行安装程序，安装程序正常。

详细信息错误是：

我必须设置如何从网页中的安装按钮单击安装setup.exe？

提前致谢

Answer 1

如果您的浏览器尝试下载setup.exe文件而不是开始安装，那么根据我的经验显示，主要有两个可能的原因。

首先，你可能没有使用IE浏览器。我只是设法用IE正常运行ClickOnce，其他浏览器都没有运行。

其次，您没有定义正确的mime类型。对于Apache（可轻松移植到IIS web.config），我在.htaccess文件中使用此配置：

AddType application/x-ms-application application
AddType application/x-ms-manifest manifest
AddType application/octet-stream deploy

这适用于IE，但是，我从未尝试使用本地Web服务器。在本地，我通常只需运行.application文件来测试设置。

尝试部署要下载的文件时，clickonce安装失败
