Installation Failure VB 6.0.4 on Windows 10

[Joerg_EQ]

I'm not able to install VB 6.0.4 on Windows 10
- at first install I could not install the network drivers (even not create the network interfaces after install VB)
- I have uninstalled VB (without error messages)
- if I try know to install VB again, the installation failed and will be rolled back

If I look at the log file (I run the installation manually with -l option) I could see also that the host only network interface creation failed. But this was not the reason for the fatal error which cause the rollback.

Any hints what I could do? (I need to install an Oracle 18c XE as VM).

I have added the log file.

1. Uninstall VirtualBox. Your VMs are going to be untouched. Reboot.
2. You may want to clean up your registry and/or filesystem at this point. CCleaner is a freeware utility that could help you. Mind the installation, it comes with "offers" from 3rd parties, known as "bundleware". Also, check out Device Cleanup program that helps you to remove any unused devices from your computer, mainly multiple "Host-Only Adapter #n".
3. Download (if you haven't already) the latest VirtualBox and its matching ExtPack. Store them in a common location, i.e. not on "Desktop", or "Documents", but to "Public/Downloads" for example.
4. Uninstall (don't simply disable) all 3rd party antivirus. If you're afraid about your computer being vulnerable, pull the Ethernet plug, disconnect your WiFi, don't go browsing around.
5. Locate the downloaded file in Windows Explorer. Right-click on the installer and select "Run-as-Administrator", even if you are the administrator. At the end of the installation, choose to "Start Oracle VM VirtualBox". Do not worry if your VMs do not show up.
6. If you're going to install the ExtPack, go to File » Preferences » Extensions. Click on the icon with the orange, down-pointing arrow on the right. Select the ExtPack from the previous steps.
7. Quit VirtualBox. Re-start VirtualBox as you would normally, i.e. from the Desktop shortcut or the Start menu.
8. Update the Guest Additions (GAs) in your guest(s), if the GAs are available for a specific guest.

to add to point 2....

Open up regedit, make sure "Computer" is highlighted.
Ctrl+F -> "virtualbox"
delete every key unique to virtualbox. For keys that are in a parent folder that has other, non-virtualbox keys, just delete the virtualbox key and leave the parent alone.

CCleaner is good but does not remove every single vmware related key.

By going into regedit and manually searching for and removing virtualbox keys after running ccleaner... this is what ultimately fixed my missing virtualbox network adapter issue.

Sorry, I was "offline" ...

The registry and device cleanup helps. The installation doesn't finish. But after abort it, I could use VB. I have a Windows 10 VM with NAT running ...

Thanks!

The installation doesn't finish. But after abort it, I could use VB.

What does "doesn't finish" mean? Do you have to "kill" the installation? That's on the borderline of dangerous, some components may not have been installed, which might bite you in the future, keep that in mind...
