I'm not able to uninstall latest release of Virtual Box. I want to uninstall because each time i want to stop my PC since installation i've Windows 10 blue screen (crash). I noticed that also i've crash once i disable the network card : VirtualBox Host-Only Ethernet Adapter which is enabled and active after windows reboot. Also i tried to launch windows in mode reduce without network and also even if network card is uninstall i've crash. If i try to reinstall a new release (dev release latest for exemple) it does not succeed because installer wants to desinstall old release but this crash windows 10, so how to proceed please ?

My release is : VirtualBox Graphical User Interface Version 6.0.8 r130520 (Qt5.6.2)

I've Windows latest with latest patchs

Thank you for help

What do you mean "I'm not able to uninstall"? Are you getting an error somewhere along the process? From the Windows Installer?

It's usually better and faster, if issues get first addressed in the VirtualBox forums, a lot more eyes there. More than 95% of the issues are resolved in the forums, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

Thank you The error during uninstall is ‘there’s another instance of installation on going’ do you want to close or continue ? If you continue previous install will be removed’ but if I continue during removal of previous instance windows 10 crash I’ve blue screen ... if I close it (first option) uninstall without doing nothing.

Please help

That's clearly a Windows installer issue, not a VirtualBox one.

Did you try to reboot your computer and when back online go straight to the Control Panel and start the uninstall process? Without double-starting it?

You may have to clean your Windows Installer Database, search the web for (several) how-to, including from Microsoft.

I believe this ticket should be closed as [Invalid].

Sure i rebooted & same.

Before installing Virtual Box my PC was running fine, since i installed it crash at each power down, please i don't think ticket need to be closed unless we identify the problem.

Also i installed some clean tools of Microsoft and also once repairing database it crash windows I've problem only with virtual bow other software can be desinstalled.

Also it there's some inconsistency why do you say its Windows, it's because of interaction between Windows and Virtual box that there's this problem ...

So please i need to have a support until the problem is closed i face a problem which appeared since installation of Virtual Box.

Thank you.

Based on the discussion/analysis in the forums, this was an overzealous Avast antivirus that didn't allow the removal of the HostOnly network card. Nanny software once again messing with the system... :/

This ticket can be closed as [Invalid].
