My problem was that the disk was mounted noexec, and the OS refuses to run scripts that are located on partitions mounted noexec. From my history file: 334 . /media/MATHWORKS_R2009A/install In fairness to previous responder James, I am not 100% sure he is wrong, since the final form of the command I ran was indeed 366 sh /media/MATHWORKS_R2009A/install & But I am pretty sure I had tried that form previously, and failed until I invoked: 365 mount -o remount -o exec /dev/scd0 I am going by memory on that, because I was swapping shells in a way that makes my history file sort of spotty. So it is just possible he is right. So if someone finds themselves with a script on a DVD that spouts this error message, they should try both the fixes and see which one works. Or both? Dave
