FAQ - Installation and Running

  • On MacOS
    • You need to accept unknown developer certificates.
    • You need to move AutoFOCUS3 to your application folder.
    • If you get an error message on startup which says that AutoFOCUS3 is broken and cannot be started: open a terminal and use the following command:
      • sudo xattr -rd /Applications/
      • As our software is a scientific prototype, our product is not signed which causes a problem due to the security restrictions of MacOS
  • On Windows: DSE does not execute and throws exception
    • If you encounter the following exception when running a DSE you might be missing required libraries:
      java.lang.UnsatisfiedLinkError: [...]\plugins\[...]\lib\x64\msvcp120.dll: Can't find dependent libraries
      Installing the Visual C++ Redistributable Packages for Visual Studio 2013 fixes the problem.
  • AF3 does not start
    • Check, that the path to your AF3 (including the AF3 folder itself) does not contain spaces.
    • If the product does not start because the Java Virtual Machine (JVM) could not be created: Please update your Java installation to Java 11.0.7
  • Unpacking of AF3 zip file fails with 'Path too long' on Windows
    • Workaround: Unzip into your drive root, e.g., C:/ and give the folder a short name like 'af3'
  • Menu icons are not displayed on KDE
