Ignore the error report, it's just from the side of microsoft that doesn't aknowledge the existence of products made with clickteam fusion.
Clickteam Fusion products are trustable, and if you are afraid, just use a regular antivirus program to check the file, and if you find any potential threat, inform me please and I will recompile this computer game again after I would scan check my computer and clean it from any potential virus.
Right now, I suppose that the file is safe, only microsoft doesn't aware much about Clickteam who made the software I use so you get the error message. It has no significant effect on the game, just accept running it, turst Clickteam, they are reliable and I work with them many years. The problem is on Micorsoft's side because they aren't aware of Clickteam since it is a very small niche company.
Enjoy this game. Fellow user!
