OpenVPN Support Forum

Hello,

"An error occurred installing TAP device center"

I'm having this problem during the install of openvpn.... I've tried everything so i came here to have some help.

I'm on Windows 7 64 bits. please .

Are you installing with the 686 executable?
Try to run as admin, to see if that helps.

I already tried this, still get the message during the install

What does it say right before you get the error? Is a dialog box that pops up and that is the only message? If I remember correctly there is a status log that displays what is happening. Maybe post this?

A while ago I had a similar problem on XP.

Disable antivirus?
Disable UAC?

Are you reinstalling or upgrading a previous openvpn installation? If so, make sure everything is deleted before reinstall.

That looks interesting. Why are you installing into the x86 directory? I am running win7 64 and it installs into the non-x86 directory. Did you completely delete the program files(x86)/openvpn directory before you tried to reinstall?

Do a complete uninstall and delete any openvpn directories. Then use the current stable version (not the x86_64 but the x686 version). Maybe it is looking there first when it is either not in that location or there is an older installation that you have.

Experienced this error on Windows Home x64

OpenVPN installation: Unable to install TUN/TAP driver. Exit code 2

Noticed the Network Adapters was empty under "Change Adapters Settings" even though the adapter was running and working.

Locate and then delete the following registry subkey:

HKEY_LOCAL-MACHINE\SYSTEM\CurrentControlSet\Control\Network\Config

I'm having the exact same problem. I tried looking for the indicated subkey but its not there. I deleted the \Program Files (x86)\OpenVPN directory as I'm running Windows x64 as well. I also noticed it is attempting and failing to create a device every time I run the install the result is an "unknown device" under Network Adapters in Device Manager.

The exact text of the error message is:

Unable to install TUN/TAP driver. Exit code: 2

The same problem for me

In safe mode I also get error installing TAP device

I have done everything that I find in internet.

I don`t have antivirus software, windows defender is also disabled.
I have tried manually install TAP driver, use different versions - nothing works.

So, I've had this issue numerous times and I just had it again. However, the fix I posted on the official bug report here https://community.openvpn.net/openvpn/ticket/592 worked again for me.

I stopped all virtualization software and kicked off the install again (didnt even have to reboot). The install went through just fine. The only virtualization software I use is VirtualBox and Sandboxie. I stopped Virtualbox machines and closed all Sandboxie Sandboxes.

It's most likely a driver conflict with another software. It's easily reproducible by just using the above software. I'm guessing it's mostly Sandboxie in my case. It may be something similar for everyone else. Check all of the services you have running in services.msc. Another way to try and help diagnose it would be using Process Monitor to monitor any errors that appear to come from the installer while you're installing.

BTW, this was with the latest version as of July 3, 2018: 2.4.6.
