After the installation of the current version v2.39, no pdf files can be opened.
Although Ghostscript 9.20 is already installed, it works fine with Ghostview.

Could you confirm that you have GhostScript 32-bit installed?

XnView Classic, as 32-bit software, can only interface with 32-bit GhostScript and plug-ins even when run on Windows 64-bit ...
