PackageCode is not unique error when buiding patch

[digitalman]

I tried my first patch and am getting an error that the PackageCode is not unique. Any ideas?

I changed the version of my original project (after copying the output from build to a version 1.0.0 folder) to 1.0.1. When I click "Save" it asks if it should create a new ProductCode and I choose "No" as it states in the documentation. I then build the project. I create a new patch project and point to the new MSI and then to the original MSI. When I click build and choose the mspmsi.exe I get the error.

Ok, I deleted the patch project and tried again from scratch and it seemed to work this time.
