Generate a new GUID form the Command Line

Is it possible to get IA to generate a new GUID when running a command line build?

We need to be able to install multiple versions of the software so each new build has to have a completely new Product Code.

Cheers

If you want to install multiple instances of the same setup - think of it as, for example, installing a master instance of SQL server, and the other named instances after it - you need to use Instance Transforms. Instance Transforms are only supported with Windows Installer 3.0 or higher, therefore won't work with Win9X operating systems, and require you to create instance transform files, and also need you to follow certain strict package authoring guidelines.

Sounds like rocket science, doesn't it? Well the good news is an upcoming InstallAware update supports instance transforms on ALL Windows Installer versions, on ALL operating systems, and with a single script command called Transform Instance. Once again affirming our slogan, Windows Installer without Rocket Science

Please contact me privately for details of this update and availability as I cannot discuss it publicly as yet.

If, you meant something else, please let me know.

You are quite correct, the Instance Transform stuff means that I do not have to do this.
