When an applicaiton is installed using a transform how does windows installer keep track of the transform? While trying to uninstall an application I receive an "error applying transform". I've been unable to find how windows is determining what transform to apply. The msi and transform are located in the C:\Windows\Installer directory and I can open the MSI in Orca and apply the transform in that folder without a problem.

theres some more useful info here about each product.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products

Sample app

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\00002109030000000000000000F01FEC\InstallProperties

this is a packed product code.
