afni.nimh.nih.gov

Hello all,
I've installed a build of Vector Linux in VirtualBox, so I can run AFNI from a windows machine. I chose Vector Linux because I was told it was user-friendly and resource-lean. I have Windows 7 64-bit.
I downloaded the "linux_gcc33_64" version of AFNI, unzipped it into a Linux directory, and set the path.
When I try to run AFNI, it tells me it fails to execute the binary?
What am I doing wrong?
Help!

Thanks!
Omer
