Unable to start any VM

[iMarble]

The VirtualBox fails to start any VM and fails with error code 1. The hardening log is attached.

There's not much that I can see wrong in the log. Please see Diagnosing VirtualBox Hardening Issues, post 4 and the last paragraphs of post 3, especially regarding any extra secutiry software you may have installed, beyond built-in Windows Defender.

I tried following things to solve the issue but in vain

• Reinstalled VirtualBox.
• Created VM again and again
• I don't have any windows defender or web safe browser
• Tried disabling Hyper-V
• Tried running "sfc /scannow" without any luck

Thanks.

I don't have any windows defender

On a Windows 11 host, yes, you do. It's Windows' built-in AV. But it doesn't interfere with Virtualbox so you don't have to do anything with it.

We'll need to wait for a forum guru to see if there's something else in the log that can be seen.

Meanwhile, if your host has the ability to boot from a separate hard drive, you could try installing Windows 11 again, and only Windows 11, on the external drive, and then Virtualbox only, and see if Virtualbox can start a VM. Windows with no other software should not have any hardening problems. Then you can add your other softwares, one at a time, and after a reboot try Virtualbox. The software causing the hardening problem should become evident after its install.

Alright, thank you.
I intended to write "3rd party defender"
Also i used the VM fine a day before this error and it was working good on windows 11. It refused to boot this morning and I haven't installed any other application in between.

This could indicate a failure to properly install Virtualbox, or to have uninstalled a previous version properly if it was an upgrade.

1. Uninstall Virtualbox and reboot.
2. Go to "C:\Windows\System32\drivers", look for any files called 'Vbox*.sys' (there could be up to 5) and delete them.
3. Reboot again.
4. If you have any 3rd-party security or anti-malware software, disable the living daylights out of it for a moment.
5. Reinstall Virtualbox using right-click-Run-As-Administrator.

No luck

OK< I'm stuck then. Try the external drive experiment if possible.

Note that this is being caused by some other software on your computer. Maybe if you start uninstalling them one at a time (after a suitable reliable restorable host disk image) you might find the one that's blocking Virtualbox.

LoadLibrary "C:\Program Files\Oracle\VirtualBox/VBoxRT.dll" failed (rc=126)

This log message is the key. The signature of the VBoxRT.dll library was successfully verified shortly before trying to load it, meaning that the file existed. So either Windows couldn't load one of the dependencies of the library, or some so-called security software prevented Windows from loading the library itself.

Two of the dependencies of the VBoxRT.dll library are vcruntime140.dll and vcruntime140_1.dll, and the second one wasn't found earlier. Therefore, I'd suggest to try re-installing the Microsoft Visual C++ 2019 Redistributable Package (x64) on your host.

THIS WORKED!
Repairing the Microsoft Visual C++ Redistributables fixed the error and now I can boot the VM <3.
Thank you So much

fth0, that's brilliant! Excellent!

If you'd like, the Diagnosing tutorial is unlocked, if you want to add this to the Exit Code 1 post.

FWIW, I've written Re: Diagnosing VirtualBox Hardening Issues, so you can forward link it from Error Symptom 1: Exit with error code 1 if you like it.

Thanks muchly, will do!
