Last Windows 10 update broke PDF24 Creator 8.41. When saving to PDF - states "file not found". Installing 8.42 does not help. PDF24 Creator 8.41 still working on other computer (hasn't obtained latest Windows 10 updates yet). Other PDF printers work fine - just not PDF24 Creator.

A reinstallation should normally help. Please also try to use the current version 8.6.0. What you can check is the PDF24 Windows service. This service should be in the running state, otherwise the PDF printer will not work.
