Something I'd like to see worked into WPI is the ability to use relational file pathnames for installs so that once you've created your custom install set and theme it doesn't matter where you run the install from (eg: CD, network, local HDD, USB HDD.) With relational pathnames for third party installation files WPI would be infinitely portable. I understand that WPI is supposed to be supplemental install system for after the Windows Installation completes, but it would be nice if it weren’t limited by specific file locations. I've already read the thread on network installs and specifying file locations that simply point at drives then use specified folder locations. But what if WPI simply looked for installations in relation to where the WPI.hta or WPI.cmd runs from? If wpi.cmd is located in at %cdrom%\wpi and your installation files are located in the folder %cdrom%\installers\ --- why not use the relational pathname "..\installers\program.exe" in the command field? Using relational pathnames would mean you could take a WPI install to any media or system and make it work without having to build multiple packages of the same data for different installation scenarios. Some machines have DVD drives, some don't; some machines have network access, some don't; some don't have a local media drive of anykind and require the use of an external USB drive to perform program installs. With the present system, each of these scenarios requires a separate build of WPI to point at the right installation file locations. Unless I'm mistaken--but I've tried many different permutations of a relational filename path and none have worked. If this is an unreasonable request as an additional feature---sorry. Adding this feature would be an amazing addition to this application. It would save developers (like myself) a lot of development time putting together multiple WPI profiles.
