Photo Paint X5 on W10 starts up then closes with no user input. Designer X5 and Draw X5 work correctly. Is there a setting, or something in the registry that needs to be adjusted? Photo paint did work for some time.
Check you've got all the updates.
You may need to run X5 in compatibility mode for Wiidows 7 or XP
Start PPX5 with F8 held down - this returns all settings to default
Run a "repair" of the X5 installation
