Hello and welcome to our forums,

This error occurs when you try to install two packages with the same Product Code, but with different configurations on the same machine.

Please keep in mind that a patch means the diff between two different versions. A patch can not be installed alone, it can only be installed if the previous version is already installed on the machine. In order to create a patch, you need two different versions of the same product, which have the same ProductCode. Let's say you have version 1.0.0 and 1.0.1, having the same product code. If version 1.0.0 is installed on the computer, the version 1.0.1 can not be installed due to the fact that the two versions have the same Product Code.

In order to avoid this, when you are prompted to generate a new Product Code, click on the "Generate New". That way, you will create a Major Upgrade. A major upgrade means the removal of the older version of your product and the installation of the newer version.

Hope this helps!
