I am currently working in a WiX/Burn Managed Bootstrapper Application and cannot figure out how to get the local path for a payload (MSI).
I let the user select which applications they want to install in my custom UI, and I want to not show applications for which the MSI is missing. I also need to see information in the MSI's database.
I know I can determine missing payloads by handling "ResolveSource" but that doesn't happen until right before the application in installed.
I deserialize the BootstrapperApplicationData.xml file first thing so I have information about which MSIs MIGHT be installed, but it still doesn't help me determine the source of the MSIs.
Does anyone know how to determine the local path to a payload?
EDIT: Here is an example for how I reference all the installers:
<MsiPackage Id="AppName"
SourceFile="$(var.ProjectName.TargetDir)ProjectName.msi"
Name="MSI\ProjectName.msi"
Compressed="no"/>
