I have a friend who's getting the same error. I've been trying to find out what one it is, too. She can run a blank exported .exe, but if I take out everything from the .cap except the sprites, it still crashed. Does construct continue to include the plugins even if the objects have been deleted?
So far, it's one of these:
sprite (doubtful - I played another game on her comp with sprites and it worked)
gradient
canvas
mousekeyboard
box
Pivel shaders:
glow
additive
overlay
color filter
bullet movement
I think that's everything.
Edit: I exported the .cap after deleting everything from it, and it's substantially larger than the other .caps I exported (the ones that are blank except for a box, etc). It would seem that plugins are left in the .cap.
