Hi, I hope that I am at the right place. Installing Openvpn 2.3.13 failed on win10 with this error message, after two successful installations on other win10 systems. "An error occurred installing the TAP device driver." Installing TAP separately fails with the same error message. In addition, the log shows this sequence at the end: "Updating drivers for tap0901 from C:\Program Files\TAP-Windows\driver\OemVista.inf. UpdateDriverForPlugAndPlayDevices failed, GetLastError = -536870330 tapinstall.exe failed. tapinstall.exe returned: 2 tapinstall cumulative status: 2 Created uninstaller: C:\Program Files\TAP-Windows\Ininstall.exe Completed" What is going wrong here? What does the error code mean? I tried several things: - Openvpn connection to my external server is not possible - Avira Services deactivated - Windows firewall deactivated - reboot The error code cannot be found with Google.

Try: "Add new TAP Virtual ethernet adapter" -> Run as administrator

Done by starting C:\Program Files\TAP-Windows\bin\addtap.bat as administrator. Same error message.

In the meantime, I spent hours and tried a lot of things, no success up to now. I noted that the driver is not in windows registry. Based on https://support.vpnsecure.me/articles/getting-started/windows-10-no-tap-adapters-found I see 13 entries in registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\xxxx where xxxx = 0000 .... 0012 None of them can be attributed to TAP-Windows Adapter V9. I followed the instruction given by the link above (which is not very clear), with no success. On my other win10 system, I see 17 entries, and entry 0015 can be attributed to the TAP driver. There, all works fine. Other attempts (reboot, windows secure mode, clean registry with ccleaner ...) were unsuccessful as well. So, my question is still the same. What is going wrong when installing the TAP driver?

I have the same problem installing the TAP driver. I get the same error messages as mentioned by hermy9. It appears to be some problem with certificates: From setupapi.dev.log: ! sig: Verifying file against specific (valid) catalog failed! (0x800b0109) ! sig: Error 0x800b0109: A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. I tried uninstalling, rebooting and installing (as administrator) several times, both OpenVPN and TAP separately, but I can't get it to work. My colleagues have exactly the same computer and they don't have any problems. hermy9, did you ever manage to solve this problem? Does anyone else have any suggestions on what to try? TinCanTech, where should I right-click for the option that you mentioned?

Windows Menu -> Tap Windows -> Add or Remove Tap Adapter Must be [i]run as administrator[/i].

Thanks for your reply TinCanTech. Unfortunately it is not working. I ran it as administrator, but I get the following error message: "C:\Windows\system32>rem Add a new TAP virtual ethernet adapter C:\Windows\system32>"C:\Program Files\TAP-Windows\bin\tapinstall.exe" install "C:\Program Files\TAP-Windows\driver\OemVista.inf" tap0901 Device node created. Install is complete when drivers are installed... Updating drivers for tap0901 from C:\Program Files\TAP-Windows\driver\OemVista.inf. UpdateDriverForPlugAndPlayDevices failed, GetLastError=-536870330 tapinstall.exe failed." Do you have any other suggestions on what I could try?

This bug has never been properly diagnosed - You may find some information here: https://community.openvpn.net/openvpn/wiki/281-what-to-do-if-the-installation-of-the-tap-win32-driver-fails https://community.openvpn.net/openvpn/query?status=accepted&status=assigned&status=closed&status=new&status=reopened&keywords=~TAP&col=id&col=summary&col=status&col=owner&col=type&col=priority&col=milestone&desc=1&order=id

Srry for bumping an old post... but keep getting this bloody error. Openvpn work flawlessly on my colleagues pc and we have exactly the same model. Any help will be greatly appreciated.

There will be a new release of Openvpn very soon with updated TAP driver, hopefully these installation problems will be resolved.

I had the exact same problem: The TAP driver wouldn't install on my PC, while my colleagues with the same model PC didn't have any problems. In the end I solved the problem by resetting my PC in such way that it kept my personal files but uninstalled all installed programs/apps. I then installed OpenVPN first before re-installing the other programs. It was a some work of course, but I'm happy that it works now.

TAP installer failed on Windows 10

I have got rid of the problem by starting msiserver service. https://thegeekpage.com/windows-installer-not-working/
