(preface: I'm not at all familiar with Windows, so bear with me) Hello, my current OpenVPN installation is borked, I can't connect to any server (I don't have the original error message in mind). My idea was to simply reinstall OpenVPN hoping that this would fix my issues. So I opened the Windows settings, clicked on Apps > OpenVPN > Uninstall. However, removal failed with this error: [img]https://imgur.com/download/tMEes4v/[/img] However, installing a new version of OpenVPN doesn't work either: [img]https://imgur.com/download/sDZxrjF[/img] So I removed the folder where OpenVPN was installed in, however, that didn't fix anything either.

It is hard to say what is going on without seeing logs. To collect logs: 1) Install OpenVPN from the command line: [code]msiexec /i OpenVPN-2.5.2-I601-amd64.msi /L*V install.log[/code] 2) Post here (or somewhere) install.log obtained from previous step, as well as [code]C:\Windows\INF\setupapi.dev.log[/code]

Hello,

What can I do now? Thanks for any help in advance.

TinCanTech

Do you have a third party security product running ? Like Kaspersky

scrouthtv

Nope, just Windows Defender

TinCanTech

Try installing an older version, 2.4.x

scrouthtv

That worked. Should I just stick with 2.4.x?

TinCanTech

It would be better if we could work out why 2.5 fails but I don't really have any ideas ..

You did not actually state the version of Windows you are using.

scrouthtv

Windows 10 Version 2004 OS Build 19041.985

TinCanTech

If installing 2.4 worked then you could try uninstalling and then install 2.5

I know these are basic steps but I don't debug Windblows.

scrouthtv

No, installing 2.5 still does not work:

OpenVPNMSICA: tap_create_adapter: DiInstallDevice failed Error -536870397

I posted a question to the users mailing list but have had no reply in 24 hours.

Sorry for the late reply. I just tried 2.5.3, and it fails with the same error.

Are you familiar with Linux ?

It is not too difficult to build a Windows Openvpn Installer for yourself, and if you try it then you can build a .exe installer.
If that works then it would probably indicate some issue.

If you have time to try then start here:

Reading your log, this appears to be the problem:

InstallTUNTAPAdapters: Creating adapter: OpenVPN Wintun Wintun 
InstallTUNTAPAdapters: Creating adapter: OpenVPN TAP-Windows6 root\tap0901 
Error 2551. OpenVPNMSICA: tap_create_adapter: DiInstallDevice failed  Error 2: The system cannot find the file specified.

Line 1307

According to logs, the bundled TAP driver is not getting installed and missing during device setup.
Not sure how this is an installer hickup or something more sinister…

A broken old TAP driver is still there but unusable (oem1.inf -> 6c3b121e4e82e247, v9.23.3, likely OpenVPN 2.4.7 or older).
Purging it may be possible via pnputil /delete-driver oem1.inf /force.

First related entry in setupapi.dev.log is SetupCopyOEMInf (line 143) for Wintun 0.8.
The respective operation for TAP v9.24.6 is not executed.

scrouthtv

> pnputil /delete-driver oem1.inf /force

This command worked. But trying to install OpenVPN gives "OpenVPNMSICA: tap_create_adapter: DiInstallDevice failed Error -536870397".

Tried that, got "Assembler messages: Fatal error: bad .section directive" for openssl-1.1.1k/. I'll try to fix it.

If you provide some more details then we may be able to help ..

scrouthtv

Already opened an issue: https://github.com/openssl/openssl/issues/16259

TinCanTech

The openvpn-build-system will build openssl for you ..

BTW: There looks like a small typ0 on this page:
https://github.com/scrouthtv/easy-copy/blob/main/README.md

rf -> rm -- probably

Haven't gotten an answer from the folks at openssl yet.

Here's my problem: if I try to build OpenVPN using openvpn-build as described in the article you linked ("To build for Windows 64bit on Linux 64bit:"), I get this log:

Notice the error assembling some file in openssl-1.1.1k/. The openssl installation instructions suggest to configure it with --no-asm, but that doesn't fix my issue. Any idea what's going on here? I have mingw compilers + assembler installed.
