InstallShield DevStudio 9

[jpaxton]

With the new interface for InstallShield DevStudio 9, VBP 5.1 assumes that you are using a script-based install. Therefore, if you are using an MSI install, it will not run because it trys to locate and call the setup.rul file.

A workaround is to select the Developer option and explicitly set the compiler path in the DevStudio 9 folder.
