Issue
Some issues have been reported in a Citrix environment while attempting to create a PDF.
Solution
The Foxit PDF Editor Creator package (PDF Printer) is a stand-alone package that was created to assist in Citrix environments. In a Citrix environment, Foxit PDF Editor Creator would be installed on the Host OS while Foxit PDF Editor would be installed (without the Creator option) on each VM. While Foxit PDF Editor Creator isn't licensed separately, neither can it be used independently of Foxit PDF Editor.
That means that it can't be added to Reader to create a virtual printer.
If you are in need of a PDF Printer for non-Foxit PDF Editor users, I recommend using Microsoft's Print to PDF virtual printer. While not as robust as Foxit PDF Editor's Creator, it will help with basic PDF creation.
Please view a separate KB article to install Foxit Foxit PDF Editor without the Creator option for a Citrix individual VM.
