Print to PDF-XChange Lite printer crashing Outlook 2016

[libove]

On a Windows 10 Pro 64-bit system, trying to print from Outlook 2016 to the PDF-XChange Lite printer (that is, open an email item in Outlook, select Print, and try to choose the PDF-XChange Lite printer) instantly and reliably crashes Outlook.
I can print to the PDF-XChange Lite printer from another program (Notepad).
This occurred with whatever latest V6 of PDF-XChange I'd had installed, and now just after updating to V7 of PDF-XChange it continues to happen.
Installed software:
PDF-XChange Editor V7.0 build 323.2 (Dec 20 2017; 15:37:43)
Outlook, Office Professional Plus 2016, Version 1711(Build 8730.2165 Click-to-Run) [Monthly channel]

Interestingly, when I try to see the printer properties for the PDF-XChange Lite printer, I get "C:\WINDOWS\system32\rundll32.exe Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." (But, as noted above, I CAN print to this printer from Notepad).

ideas?

thank you,

Hm. Problem stopped after a reboot.

Hi libove,

That's very unusual and we've not seen any other reports, to the best of my knowledge, but I'm glad the reboot fixed it. For now, we'll treat it as a strange one-off, but should it start happening again then please do let us know!

Cheers,
