How can I get an application's GUID from an MSI file without installing it and searching for it in the registry? Is the GUID located in the MSI's properties? Or, can I retrieve it using Orca?

It's in the "Property" table, property name "ProductCode". What exactly do you need to do? – jscott Feb 28 '13 at 15:32
Remove an application that isn't getting uninstalled automatically in group policy. – Force Flow Feb 28 '13 at 15:36

If you can use orca, the Property table has the product code.

There's a ProductCode and UpdateCode, which are different IDs. What's the difference between the two? – Force Flow Feb 28 '13 at 15:35
ProductCode uniquely identifies the "version" of the software. The UpgradeCode is used by the Upgrade table to determine which versions can be upgraded. – jscott Feb 28 '13 at 15:39
