Yes, PDFCreator is really free and may be used without paying money to the authors or anyone else and your rights on the documents you create with PDFCreator are not changed in any way. That does not mean, that PDFCreator has no license. Just these licenses grant you the right to use PDFCreator and to give it to anyone you like without charge.
Although PDFCreator is free, there are some restrictions compared to the paid editions. Apart from several features, PDFCreator Free can not be installed silently on machines that are part of a Windows domain. In those cases, the installation has to be interactive. Further, Windows Enterprise Multi-Session support only extends to the business editions of PDFCreator.
The PDFCreator Setup is a package of multiple software components. The PDFCreator team took care to only require components, that are free. Each component has it’s own license.
Each license allows to download, install and use PDFCreator in a private or commercial environment. They also allow to distribute PDFCreator to as many people as you like, if it is free of charge. The licenses do not interfere with your rights on the documents you process with PDFCreator - they will always be yours.
