1. You don't have to use the PBD file, you can also use the PBL file. That way it won't have to be a PBD which was compiled for exactly your version and build of powerbuilder 2019.
2. Don't forget to also copy the PB2XLS.dll to your folder. If you are creating a 64 bit executable, you have to copy PB2XLS_64.dll to the folder where your EXE file is and rename it to PB2XLS.dll
