If none of the above worked, just drop us an email attaching the not-so-enlightening debug messages in your shell window, we will try to figure out what is happening.

Take a look at those messages and see if there is some enlightening information that can explain what is the issue. You will find two files called pdfsam.sh for Linux systems and pdfsam.bat for Windows systems, run/double-click the one for your system, a shell/ Command Prompt window will open, PDFsam Basic will try to start and a number of debug messages will show up in the shell window. If that didn’t solve the issue you can try running PDFsam Basic using a startup script we provide in the bin subdirectory. We do all sorts of checks during the installation process and during the startup of the application to make sure we inform the user if Java 8 is missing but there might be some exotic case we missed, so first thing try upgrading Java to its latest version.

Is to make sure a Java Runtime version 8 or above is correctly installed on your machine (Java 8 is a requirement given PDFsam Basic is written in Java).

Sometimes it can happen that PDFsam Basic doesn’t start and there is no error message or anything that could help you understand what is the issue.
