Nitro Pro 12 Unable to Print and Save to PDF

[ITC Support]

Hello, my client is experiencing an issue where he is attempting to print to PDF, but it will not move past the print queue, it just stays stuck at the "sent to printer" status.  I've updated to the most recent version: 12.16.3.574 and attempted a clean install, repair and other troubleshooting.  No steps taken have gotten us any closer to actually be able to print to PDF and save them onto his desktop.  I am a bit disappointed with the lack of responses and support so I opened my own thread in hopes someone would respond.  Please advise.

Hello @ITC Support,

Thank you for reaching out to us through our Community Forums and our sincere apologies for this inconvenience.

In order for me to further assist you with your concern, could you please provide the following?:

-Is this a new issue or has it occurred since after installing Nitro Pro? Any changes you are aware of before this happened (e.g. Windows Updates)?
-The serial number of your client's Nitro Pro 12. To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'. 
-Does this happen with every file? If it is a single file, please send us the sample file (with sensitive information extracted) by sending me a private message so I can replicate it on my end. 
-What is your client's workflow when printing to PDF (e.g File> Print > PDF Creator)?

Thank you very much in advance and I am looking forward to hearing back from you.
