4.0.6 update - guest additions install fail

[TheOtherPhilC]

Windows 7 x64 Host. Win7 x86 Guest. Everything running smooth on 3.2.

Installed 4.0.6. Started guest. Logged in OK. Everything fine. All integrations working. Message pops up about down level guest additions. I click Install Guest Additions on the menu. It churns away and seems to install OK. When it finishes, Windows puts up the "must reboot" message with options to reboot no or wait until later. I click reboot now. This is where the trouble started.

The host froze. No mouse. Nothing. Machine clock stopped. (This has happened several time in recent weeks, with no Vbox involvement. The freeze was probably not caused by VBox.)

Reset the host (the only way out). After host rebooted, started the guest VM. Guest Windows started a chkdsk on C:, found numerous orphaned files and fixed the errors. Finally booted up ok. Message pops up again about down level guest additions. So, I once again click the menu option to install guest additions. This time the install failed with the log displayed as in the attachment.

I rebooted and tried again to install 4.0.6 guest additions. Same result.

I then uninstalled the previous guest additions, and repeated the above. Same result, except now I am in worse shape because all integrations are gone. Latest attempt was in Safe Mode, by navigating to the install EXE on the virtual CD/DVD and running it as administrator.

Is there any way out of this?

A bit more info.

In the device manager on the guest, I discovered the display adapter had a yellow icon attached. In the properties I found the message:

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"

I guess this VM is corrupted beyond recovery.

Let's hope you have only lost the guest OS. Sounds like your host OS/hardware isn't too flash either, if it hangs regularly.
