Do you have one of the databases open in Orca (or another tool) while running your code?

Subject: [WiX-users] CreateTransformSummaryInfo Error Hi, If I use the following line of DTF code : targetDb.CreateTransformSummaryInfo(sourceDb, transformFile, TransformErrors.AddExistingTable, TransformValidations.Product); I get the following error : This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package. The source and Target msi files are very basic (based on Schema.msi). The only difference in the Target msi is an extra entry in the Property table. What I'm ultimately trying to achieve, is the ability to modify existing MSTs and automate application of our company's packaging standards.
