No, I don't use any anti-virus software. Also the game builds and plays just fine. It's the WACK giving mixed results every time. The lack of official help for such technical problems is very disappointing especially when there is a contest with a deadline. If you guys are doing these contests to encourage people to work on games for a specific platform, you should help them out with such strange technical problems. Otherwise people will just target other platforms with more streamlined build processes. I had to crunch for the whole month of January to get my already WIP game into a shape that's playable for this contest. I may come off as ranting here but these are my sincere thoughts. And I don't think I'll ever target any Windows store platforms ever, not when I have to wrestle with such incomprehensible problems and have to prepare a thousand icons with a couple pixels of scale difference between them. No porting guides, no official answers to any of the questions regarding the contest rules or any technical help that is actually helpful. I feel like there wasn't enough planning that went into preparing of this contest. One wishes that there was a dedicated team in Microsoft and Unity that processed the submissions to this contest and helped the developers with their problems regarding putting their game onto the Windows store. Because what is the goal of this contest after all? If it is to show the developers that Windows store platforms are actually easy to target and are worth it to put your game on, in my case it has failed terribly.
