What are the supported versions of Adobe Acrobat?
PDF Transformer contains Adobe Acrobat PDF Library and will open any PDF version. On the creation side the product supports Acrobat versions 1.3-1.7. By default the created PDFs will have version 1.3 or 1.4 (depending on file content) to support maximal compatibility with other programs. If you wish to select another version, you can do it by selecting PDF-XChange 4.0 for ABBYY as your printer in Print functions and defining the version in Properties.
