Are you running the MAC OS in 64-bit mode and installed the 32-bit VirtualBox bits?<br />

I've been using VirtualBox installed on my Mac Pro for over a year. I have a Windows 7 installation running on it. This morning, VirtualBox told me a new version is available. So I downloaded and installed it, ran it, tried to open my virtual machine and got a bunch of error messages and an &quot;abort&quot; button. OK, so the upgrade is no good. I downloaded a backup from last night of the Application. Ran that, tried to open my virtual machine, similar errors! So, I downloaded a backup of my virtual machine AND the application, still can't run my machine.<br />
<br />
This virtual machine is vitally important to me. I have backups of everything and still I can't make it run. This very frustrating, I would really appreciate any help in getting back up and running. Thank you!!!

VirtualBox upgrade wreaked my Windows 7 installation on Macintosh

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
