The dropdown list for Open File and Import File does not list the PDF file format option; just the PDF Placeholder option. This only happens for the installation of X15 Pro on my Workstation PC running Windows 7.

On my Laptop PC, running Windows 10, the installation of X15 Pro has no problem displaying the PDF file format option.

I tried reinstalling X15 Pro on the Workstation PC and had no luck.

Any ideas of how to fix this?
