Question

我们有一个ClickOnce组件安装在客户端计算机上，当用户单击URL（在IE11中）时，该组件在Word中打开docx文件。当我们将组件的新版本部署到我们的QA服务器进行测试时，它在安装过程中开始失败，并且使用以下DeploymentException这是没有意义的，因为这对所有先前版本都适用。

有什么想法吗？

Answer 1

嗯，问题结果与我们的ClickOnce.csproj文件中的设置更改有关，我们没有意识到这是由我们的某个开发人员签到的。具体来说，当Install设置为true而DisallowUrlActivation设置为false时，我们遇到了问题。将这些设置更改回原来修复了ClickOnce安装的所有问题：

<Install>false</Install>
<DisallowUrlActivation>true</DisallowUrlActivation>

希望这有助于其他人...
