Ok, I’m trying to export my game to a runtime, yet whenever I try, there’s an error saying “unable to open blendfile.” Can someone please help me with this?
Try running the game first, then exporting it to runtime, worked for me 
Make sure you have a file called ‘blenderplayer.exe’ in the same directory where Blender is… Usually C:\Program Files\Blender Foundation\Blender.
I remember that when I changed the name of ‘blenderplayer.exe’ to ‘blenderplayer.scr’ I could no longer make runtimes, so I just changed it back and it worked fine…
If it’s missing, just re-install Blender.
Ok, thanks.
