I received when upgrading VirtualBox.

Upgrading from: VirtualBox 5.0.14
Upgrading to: VirtualBox 5.0.18
Host: Windows 7 Professional Service Pack 1
Guest: Windows 7 Professional Service Pack 1

After I completed upgrade, a prompt occur asking whether to start VM. I clicked ok. I get the standard Virtualbox log then the screen goes black and a pop-up window shows (see attachment - error_message.png).

"Critical error has occurred while running the virtual machine and the machine execution has been stopped. ..." Request I contact Community regarding issues and post logs.

I am not sure what additional information is needed.

I am getting the exact same error, after upgrading VirtualBox to 5.0.18 as well. It only affected my Windows7 guest. My Linux guests are working fine.

I haven't fixed the issue but was able to revert to the older version which actually was 5.0.16 not 5.0.14 using Microsoft Windows System Restore Point that was just prior to upgrade.

Thanks, but we have plenty examples of this discussion topic already. See the Discuss the 5.0.18 release topic.
