我有一个使用 ClickOnce 在 Visual C# 中创建的应用程序。我通过压缩的 ClickOnce 发布文件夹将此应用程序发送给用户，但是我（开发人员）无法安装它，而其他人没有问题。

我执行以下步骤： - 在 VS 2010 中，项目设置，发布选项卡，单击按钮“立即发布” - 在创建的目录中我运行设置（这是创建的 ClickOnce 设置文件） - 我收到错误对话框：应用程序不能开始了。联系应用程序供应商。

顺便说一句，我没有签署我的申请并将该申请指定为完全信任申请。

我已经尝试过的（也根据评论）： - 当以管理员身份运行时（在本地文件夹中单击一次设置人民币），我得到了同样的错误。- 直接从 bin 目录运行时，它工作正常。- 添加睡眠以附加调试器时，它会立即给出相同的错误。- 我清除了缓存，但没有帮助。

以下是完整的详细信息：
