Hello, very good, I recently installed virtualbox version 7.0.12 and when I go to install "VBoxWindowsAdditions-amd64" I get an error,

"You need administrator rights to install or uninstall the oracle VM VirtualBox Guest Additions 7.0.12.
This application will exit now"

I don't know how to solve this problem

Someone could help me? thank you so much!

@Jose89: Like it says - you need admin rights. We don't do Windows tuition here so we won't go into details (Google will have those). In the meantime note that you can use "Run as adminstrator" to run the installer with elevated (admin) rights, if you have access to an admin password. If this was an unattended OS install and you didn't even look at the startup dialogs then the default password was "changeme".

And p.s. this was a not a 7.0.12 specific issue. Please only use this topic to discuss new matters arising from the 7.0.12 release.

Beside the flickering search menu, there are other 3d acceleration issues in the new impletention.
The canvas in paint 3d does not show up, and ms solitaire collection app does not initiate at all.
`
The workaround is `VBoxManage setextradata "Win10Test" "VBoxInternal/Devices/vga/0/Config/VMSVGA10" "0"`, and the issues above are gone now and I can even play ms solitaire collection without problems.

@eebssk1, I cannot find that setting in the Virtualbox manual. What does it do?

It reverse back the 3d impletention to the legacy 6.x one.
You can find it in the source code,it's not documented.

FWIW, I explained the VMSVGA10 setting over a year ago in Re: Square font on WIN10 since upgrade to VB7.

For those with 3D issues with Windows VMs: At least the flickering should be fixed with the latest 7.0 test builds. Update both the host package and Guest Additions inside the VM.

drm/vmwgfx: Print errors when running on broken/unsupported configs

virtualbox implemented an incomplete version of the svga device which
they decided to drop soon after the initial release. The device was
always broken in various ways and never supported by vmwgfx.

vmwgfx should refuse to load on those configurations but currently
drm has no way of reloading fbdev when the specific pci driver refuses
to load, which would leave users without a usable fb. Instead of
refusing to load print an error and disable a bunch of functionality
that virtualbox never implemented to at least get fb to work on their
setup.

Does this mean 3d accel with vmsvga will completely useless in later kernel version if virtualbox does not take any actions?

Don't ask me for the correlation between the very misleading commit message and what the change actually does.

In the end this change just disables the VMware-specific message logging and adds some messages to the kernel log but other than that I see no disabling of functionality.

Hi

I followed this reply and I could install VB Guest Additions in Windows 7 Ultimate.

Thanks!

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.

I just upgraded to VBox 7.0.12 and upgraded the VM Guest Additions on my two Win7 vms. Both are now broken. One gives errors just at the login screen, the other won't boot at all. Ouch!

[eebssk1]

Search menu flickering seems fixed. Though there are still a lot other issues.
