Building problems

Hi guys, I'm having problems in this game I'm making. The demo is almost done but I can't run a build (it's the paid version). I built other demo before and it works very well, but not this time. Any ideas??

some more information wouldn't go amiss... maybe tell us what is happening or what options/settings you used on the build export etc.

Here are the options;

What exactly means "can't run" ? Please describe the error or show a log file. If you export to files with spaces in it, it might not run because the config isn't written correctly. Please post the resulting config.ini also, that might help.

Thank you Simon S, I've built again without the spaces and that works!
