As the title says, I have been trying unsuccessfully to run OpenVPN on a Windows 7 64-bit system with the error message in the log that there are no adapters on the system; the same also happens after I install tap-windows-9.21.2.exe additionally. In Device Manager, the adapters appear with yellow triangular signs with exclamation marks, and an error message in Properties saying:
(Seemingly, it is a signature verification problem). Could anyone suggest a way to address this, or, should additional information be needed, let me know what?Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
Thanks.
