Installation Error Every Time

[Alb11747]

Describe the bug
Everytime I try to install OpenVPN I get this error "OpenVPNMSICA: tap_create_adapter: DiinstallDevice failed Error -536870397:"

To Reproduce
Download and run the installer (Though, it's machine specific).

Expected behavior
OpenVPN installs and run correctly.

Version information (please complete the following information):

• OS: Microsoft Windows 11 Home - 10.0.22621 Build 22621
• OpenVPN version: 2.6.5 to 2.5.9 (Tested on all the installers)

Additional context
It managed to get past this point even with the error but when I tried to connect it show an error that said window did not have a tap driver.

I had previously installed OpenVPN on this computer but when I got a notification that there was an update I downloaded and ran the new installer getting this error.

In Device Manager > Network Adapters, I see a "Unknown device" getting added everytime it gets to the error and removed when it rolls back the update.

I see the same issue on Windows 11 Pro with 2.6.6 with latest updates as of today on new install of OpenVPN

can you collect logs from "Event Viewer" --> "Windows Logs" --> "Application" --> (Source: MsiInstaller)

[chipitsine]

btw, do you have wireguard installed ?

[wolfgangihloff]

No, no Wireguard installed, I cannot upload in here the MsiInstaller events.evtx, but see screenshot

go to system information and check your not on an ARM64 processor if so download that version

Like @netti86 said: It's most likely you used the AMD64 installer on an ARM64 device like a Surface. Had just the same issue.
