我最初在网络工程部分发布了此问题，他们说超级用户更适合提出此问题。所以我就在这里！
我曾尝试在 OpenVPN 论坛上询问这个问题，但没有得到回复，我花了几个小时寻找答案并解决问题。我正在运行 Windows 8.1 x64。
当我安装 OpenVPN 软件时，它会一直安装到 TAP 驱动程序。然后 TAP 驱动程序就会失败。我尝试以管理员身份运行驱动程序，在属性中取消阻止它，关闭防火墙和 AV，将网络的注册表值更改为 config.bak，安装不同版本，卸载“未知”设备，删除 HKLM/SYSTEM/Enum 中的 NET 键，尝试在安全模式下安装它，禁用驱动程序签名，运行 sfc /scannow，授予 rundll.exe 权限，但仍然没有任何效果。
无论我做什么，都会出现错误。以下是 TAP 安装程序的日志：

那么对我来说，这段代码告诉我什么地方出了问题？
Sig: Verifying file against specific (valid) catalog failed! (0x800b0109)
Error 0x800b0109: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.
那么，是他们的证书还是我的证书？有什么办法可以解决这个问题吗？
所以我找到了这篇文章，驱动程序签名疑难解答并且它指出要安装一个不是“根据特定（有效）目录验证文件失败”的驱动程序。因此，我转到“添加硬件”，并说我有磁盘，然后输入 TAP 驱动程序的 .inf 文件，它指出
您指定的文件夹不包含与您的设备兼容的软件驱动程序。如果该文件夹包含驱动程序，请确保该驱动程序设计为适用于基于 x64 的 Windows 系统。
尽管下载内容显示它是针对 openvpn-install-2.3.4-I604-x86_64.exe 的。那么我该怎么做呢？
请大家帮帮我，我真的需要 OpenVPN，而且我已经解决这个问题好几天了。
提前致谢！！
