Failed to start worker process

Doum · 07-07-2020, 04:47 AM

After using 'affichage rapide' (quick view if my translation is correct) i have an error when i add a new book whith version windows 64bits

This error didn't occur with portable version 32 bits (same version, same epub)

Have you an idea please ?
