Want to find the GUID of an MSI installation
I want to be able to find out what the GUID will be for the uninstall string of an MSI package.
I want to do this without installing the package and since I have to do this for more than 100 MSIs a command line or data dump of an msi I can mine the data out of is preferred.

Without installing the MSI you can use Orca, a free download from Microsoft contained in the Platform SDK. It is the tool they use to create, edit MSI files. Once you open the MSI with Orca look in the Properties Table and look for the Prodcut ID which is the GUID you are looking for.
