If you find OCR Feeder is not launching from the Applications | Office menu in a base install of 16.04, try running it from the command line.
ocrfeeder
For a more comprehensive fix, run System | Preferences | Look & Feel | Main Menu and scroll to the OCR Feeder entry. Right click on the entry and select Properties. You may notice the executed command is expecting an input file.
ocrfeeder -i %f
Simply remove the “-i %f” suffix from the command, save and close the menu editor.
It should now run from the Applications menu as expected.
Hope this helps,
