You have to do this part only once.
Right click the file and “extract all.”
Specify a location to extract to. Note: in its efforts to be “helpful,” Windows may create a folder inside a folder to hold your files.
Open My Computer and navigate to the folder where you extracted the files.
Double-click the file named boutmaker.jar
The program should then run. When you create PDFs, they will be stored in the same folder as the boutmaker.jar file. If you get a message that says something like “Java not found” or if Windows asks you which application you want to use to open the file, then you will have to download the Java runtime for Windows.
