- Choose “Choose default program…” in the sub-menu (last entry).
- A dialog opens.
- Select PDF Studio in the Recommended Programs list or Click “Browse” to navigate PDF Studio (C:\Program Files\PDFStudio\pdfstudio.exe) if PDF Studio is not showing in the list.
- Check the box “Always use the selected program to open this kind of file”
- Click OK to close the dialog.

- Look for the line that starts with “Exec=” and add %f at the end of the line.For instance if the line reads:
Change it to:
Exec=/bin/sh “/home/john/pdfstudio2018/pdfstudio2018” %f
- Save the file
- After that, PDF Studio 2018 should show as an option under “Open With” in step 3) above.
- As a root user, open “default.list” file under “/usr/share/applications”
