accessing drive in InstallScript project

[jedimaster_mark]

Hello all:

Normally I work with MSI projects, but we maintain one (very important) project in InstallScript. This is the first I've worked with InstallScript, so I'm rather ill-versed in some of the nuances.

I have a project that can take one of two distinct install paths. The project will always be launched from a CD, and the decision on which path it takes will always be found within a file that has a known name on the CD.

So, I need to read in this text file. The problem is that I need to be able to access the CD's location. Is there a built-in property that always refers to the system's CD/DVD drive, or better yet a property that automatically refers to the location of the installer (in case the user has more than one CD drive?)?

Many thanks to all of you,
Mark

Perhaps see if one of SRCDISK, SRCDIR, or PACKAGE_LOCATION will do the trick.

Hmm, I imagine one of them should. Thanks for the pointer!
