virtualbox.org

Someone sent me a virtual box. The client showed me through a webex session how it was running fine on his computer. Unfortunately, I cannot get it to run on my Windows 7 box.
Attached are the VBox.log and VBox.png. Would appreciate and thoughts/suggestion.

00:00:00.324187 Host RAM: 4013MB total, 2480MB available

00:00:00.470551 RamSize <integer> = 0x00000000c0000000 (3 221 225 472, 3 GB)

00:00:23.807336 VM: Raising runtime error 'HostMemoryLow' (fFlags=0x2)

Memory over committed. Reduce amount of RAM assigned to the guest or free up host memory by stopping other processes.

Thanks Perry.
I decreased the memory required, and it works just fine.
