virtualbox.org

I just installed VirtualBox 2.1.2 on Ubuntu 8.10 x64. I have a Core 2 Duo processor and 4 GB RAM. I am trying to load Windows 7 x64 Beta on it but I keep getting error messages saying that I am trying to load a 64-bit application but my procesor doesn't support it.

I searched through the forums and Google but couldn't find anything with a fix. Any ideas? I'm using the default settings.

Read the chapter in the Manual about this topic. Check requirements.
