I installed ubuntu12.10 arm64 version, then installed virtualbox 64bit and win7 32bit VM. I created /mnt/share folder and shared it with win7. In win7 share folder, some exe files could be executed, but the others couldn't. The error says, the path doesn't exist. But if I copied those files into win7's own folder, it could be executed. I'm confused. Could anyone help me?
