Host-Only adapter failled to install

[AlexRoux42]

Hello,

[How to reproduce it] From fresh installation, installation was ok,I had no problem to use host-only network and the host-only adapter was present. The problem began when I removed using VirtualBox GUI my host-only adapter, I was then not able to re-create it using either the GUI and the command line.

[Similar issues] As you can imagine I've walk through the VirtualBox forum and Bug tracker before posting and I found a similar issue : + https://www.virtualbox.org/ticket/17354 + ​https://forums.virtualbox.org/viewtopic.php?f=6&t=86179 Here the antivirus was involded and disable it resolved the issue. In my case I've completely uninstall my corporate antivirus + deactivate Windows Defender without success.

[Troubleshooting] + Repair VirtualBox + Uninstall VirtualBox + Remove %userprofile%\.virtualbox + Remove drivers in %windir%\System32\drivers + Remove registry keys about VirtualBox + Install 5.2 VirtualBox + Run Installer as Admin right + Run a Ccleaner registry cleaning

With a result always the same, failed to create host-only adapter.

[other] It's just a supposition but I'm wondering if the issue is trigered also as I respond [NO] once to the UAC pop-up message asking to install host-only driver (after choosing to create host-only adapter from the GUI).

Thanks in advance for all your help, this issue is a blocker for me.
