Question

几次部署项目时遇到错误。在项目的第18版中，我注意到打开应用程序后，它不会自动安装。我试图通过运行system.application文件来手动安装它，但是很遗憾，我收到了“应用程序下载未成功”的信息。

我已经在网上搜索并确实尝试了一些解决此问题的方法，但没有一个起作用。我正在使用VS2015进行编码。

Answer 1

答案似乎在您发布的已记录信息中：您的应用程序托管在/发布到网络位置（smb文件共享？），并且消失了：

下载文件：// users / Team Guilas / Desktop / Kids / Kids监视系统。应用程序未成功
。
找不到网络路径。

检查您的网络连接，服务器可用性，驱动器映射等，然后重试？

VB.Net应用程序下载未成功
