VBox 7.0.12 GA cannot verify digital signature Windows 7

[Simple07]

Installed VirtualBox 7.0.12 and when trying to update its Guest Additions on Windows 7 I get the following error message:

"Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software form an unknown source. "

However, updating Guest Additions 7.0.12 on Windows XP and Windows 11 work fine.

I tried reinstalling Guest Additions 7.0.12 on Windows 7 few times, to no avail, but installing Guest Additions 7.0.10 on Windows 7 works fine!!

I tried a number of solutions, including registry editing, nothing worked.

But what worked for me is, start an Administrative CMD and run "bcdedit /set testsigning on"

Rebooted and successfully installed VirtualBox Guest Additions 7.0.12.

You can download the release here.

Changelog is here.

In my case Guest additions installed without any error but after restart Windows 7 fails to boot and always loads startup repair.
I used F8 to select "Disable Driver Signature Enforcement" and after boot I used "bcdedit /set testsigning on" as suggested.

It now works ok with signature disabled.

I hope we will get a new version with a fix soon. Is there a bug report of this?

Same problem with VB 6.1.48 released on the same date: guest with Windows Server 2008 R2 won't boot.
Disabling driver signature only works on the first reboot.
Disabled driver signature, uninstalled Guest Additions 6.1.48 and reinstalled GA 6.1.46 (VB also on 6.1.48, so the problem is in the GA).

All the below testing was done on Windows 7 Virtual Machine.

I tried to install Guest Additions 7.0.11-159406 on VirtualBox 7.0.12, but it gave the same message.

- Uninstalled VirtualBox 7.0.12 completely and deleted the C:\Oracle folder, installed VirtualBox 7.0.11-159406 with its Extension Pack and tried to install GA 7.0.11 and GA 7.0.12 but both gave the same error.

- Uninstalled VirtualBox completely deleting C:\Oracle folder and installed VirtualBox 7.0.10. with its Extension Pack and tried to install GA 7.0.11 and GA 7.0.12 but both gave the same error.

It looks like the error was already in 7.0.11 but not enough testing was performed.

I installed 6.1.48, then the 6.1.48 GAs into a Win10 VM, and - no problem.

How far into a boot does yours get?

Try installing GA in 64-bit W7 which others and I are having problems with. Mine always end up in Startup Repair screen after "Loading Files" screen. See my viewtopic.php?t=110349 thread.

Give me time! In fact I just tried it with a Win7-64bit guest, and now I see big problems. "Startup Repair" diagnostics says that "Boot critical file D:\Windows\system32\DRIVERS\VBoxGuest.sys is corrupt". Odd that it says D:, as the system drive is C:, D: is the CD I think (I can't boot up to check!).

Ok, got to a terminal. Weird! Drive C seems to be a virtual folder containing one file "rescuepe.log". Perhaps this is something that the boot repair mode in Win7 does. I'm about to try deleting the "corrupt" file. {Edit}Yes, that gets me in. Now to reinstall the 6.1.46 GAs! {Edit2}That worked too.

Given that the file is probably not really corrupted, I'm going to guess that it's missing a certificate that works in Win7. I don't know why Win7 considers it "boot critical" tho.

OK. At least, you reproduced the issue.

I tried again and this time tried to pause it during the GAs install so I could read the messages. I get an error that it couldn't replace "VBoxService.exe", and that after a bunch of errors concerning VBoxCertUtil.exe failures calling CertEnumSystemStore and CertOpenStore.

The final error message directs me to look at a file C:\Program Files\Oracle\VirtualBox\Windows Guest Additions\install_ui.log - which does not exist.

Let's have a look at "C:\Program Files\Oracle\VirtualBox Guest Additions\install_drivers.log" and "C:\Windows\INF\setupapi.dev.log" instead. And perhaps a screenshot of the messages during the installation process.

Edit:
Corrected the path and removed a superfluous space that crept in in front of the first file name. And added quotes.
