[quote:2xb7x7xd]Tonight, I was showing my game at an event for a couple hours already, when suddenly the game shut down. I tried to relaunch it, either the windows 32 bit or 64 bit version (it's a NW.js export) but none ever worked.
There is a log-file in the folder of your game, so you could see what goes wrong when you start it.
[quote:2xb7x7xd]I tried reinstalling the latest version of NW.js and reexporting but it changes nothing.
Did you uninstall the previous version before? Was the previous version 0.12?
For Construct 217 and higher you need 0.13 and if you install 0.13 over 0.12 you can get very bad side effects.
What you can try:
delete the folder with the name of your game in %userprofile%\AppData\Local\
(I don't know where the folder ist in Windows 10)
