Cannot install Fusion on Mavericks

I've downloaded "VMware-Fusion-6.0.2-1398658-light" but when trying to install it I get

"VMware Fusion is damaged and could not be repaired. Please move the VMware Fusion application to the Trash and reinstall VMware Fusion"

I have no prior installation of VMWare Fusion on my Mac - only an installation of VirtualBox.

I've checked my filesystem, performed permission and integrity repairs.

I have colleagues who have successfully installed VMware Fusion from the same disk image.
