I have a need to run Dyalog APL on a Macintosh. Currently I have been able to install Dyalog APL on a virtual machine running Windows XP Pro. I have created another virtual machine running Vista Business, but the Dyalog APL installer fails when I attempt to run it under Vista. The folks at Dyalog state that the have no problem running the installer under Vista running on a PC. I am wondering if it would be possible to clone my Windows XP machine and then install Vista over XP.
