InstallShield Pro 7 Question

[martys]

A few of the steps near the very end of my build are running InstallShield compilers. I have noticed that the InstallShield does not compile properly, even from the IS UI, unless I delete the Media Disk images first (even if I do a refresh build). That's a problem for elsewhere. My problem here is that even when I do delete the images, it still doesn't build correctly from VisBuild, even though it does from IS.
