Dang. I'm sure it's a false positive; this issue is known to other Game Maker Studio users (the engine used here). Thank you for reporting it and apologies for the trouble, I'm looking into it.
I just built, tested, and upload an installer file for Solumnoid instead of a plain exe (the installer is still an exe but hopefully it will be treated differently). When you have the chance please try downloading and running Solumnoid 1.0 installer from this page and let me know if you run into similar issues.
EDIT: It worked for the other person who had the issue! I'll keep an eye out here to see if the solution is the same for you.
