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)

Also tried to install other release of VirtualBox (old one and dev release and same problem)

I've Windows latest with latest patchs

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.

Also blue screen if i want to disable Host-Only Ethernet Adapter, this is may be what cause cash of uninstal (blue screen)

i rebooted Winbdows and same 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.

Please help :)

First off, I'd try a shutdown of your host using the "shutdown -s" command. Windows 10 has a hybrid shutdown, which leaves some things un-reset. The command causes a full old-school shutdown that has cleared stuck data before in my experience.

Next, the Virtualbox installer uses the MSI installer database provided by Microsoft. It sounds like the MSI databae is corrupted. Google for how to fix MSI database corruptions. Also try this:

I have two other links to suggest. See also if you have any corrupted MSI database files:

Hmm, too bad it didn't work. Unfortunately I think the Virtualbox uninstall is just showing up the problem, not causing it. Your MSI installer database is messed up somehow. It does happen sometimes. Try a Windows forum and see if they can help you get the whole installer system working again.

Your PC may very well also have a problem with the Virtualbox Host-Only adapter. Fixing that will require uninstalling and reinstalling Virtualbox, which requires the fix to the MSI installer database, which we don't know how to do here on the Virtualbox forums.

OK understood, do there's way to fix manually the MSI installer database by using some manual tools like regedit ?

Sorry, I'm afraid you've mistaken Virtualbox with Google & Bing.

What 'scottgus1' means, is that you shouldn't rely on the VirtualBox forums to get a working answer, but you should be searching for the answer using your favorite search engine.

Just out of curiosity, do you have any 3rd party antivirus installed?

That's the part that may be blocking the uninstall! Completely uninstall Avast (don't simply disable it) and then try the uninstall again, see what happens...

So you were right this was AVAST antivirus that blocked uninstall of Virtualbox and also the disabling of network card !!! I suceeded to uninstall after removal of Avast

So i think this problem can appear to other people's using Avast & VirtualBox i suggest to open a ticket to Avast ?

I suggest to never install a 3rd party antivirus on a Win10 system, it has its own, no need for 3rd party ones that mess really bad with your system.

I'll update the ticket as well to indicate that this was an Avast issue...
