openvpnmsica get_net_adapter_guid querying netcfginstanceid registry value failed error 2

desbest

Hello I can't install OpenVPN 2.5.0 on Windows 10 20H2 due to this error.

openvpnmsica get_net_adapter_guid querying netcfginstanceid registry value failed
error 2 the system cannot find the file specified openvpn

I chose to install the TAP driver and not the Wintun driver when I tried to install.

Well, which anti-virus are you using ?

I know you saw my "exploding carrots" post. :mrgreen:

For that person, the problem was inbetween the chair and the keyboard.
Yeah lol :lol: . It's amazing how people who refuse to listen to instructions, get frustrated with customer support as if it's somehow their fault, when the problem is between the chair and the keyboard.

I have disabled all components of Comodo Internet Security and I also disabled Windows Defender Antivirus and Windows Defender Firewall, and it still didn't work.

You have disabled the parts of Commode that they let you disable ... :ugeek:

I ditched Windblows all together, Linux Rules! 8-)

I don't see the point of being a conspiracy theorist. When all the components are disabled, Comodo does not interfere with the operations of installers and running programs in any way. So if it's disabled it really is disabled, with nothing else left to disable. Also not everyone has a good use for Linux.

So given that I disabled it, do you have any ideas that can fix the error?

Uninstall it.

If that does not work then you will probably have to re-install Windblows ..
and/or make a complaint to Commode.

I uninstalled Comodo and now openvpn 2.5.0 can install with the TAP driver.
But now I have another issue. I can't connect to my vpn.

Below are the errors I get.

Server log ?

desbest

I don't control the VPN server I'm connecting to, to be able to get the log files from the server. I'm just a mere customer, I'm not managing the VPN server and I didn't set it up. I pay money to the VPN provider and get given a .ovpn .p12 and .key file needed to connect to it.

TinCanTech

Sorry, there is no way for us to debug a connection without the server log.
