Hey! Thanks for supporting! You don't need anything extra for MV, my only guess is that you have an antivirus/windows defender-like program that's just automatically blocking it. Personally every time I download and test the game, it warns me if I want to open the game. I would try running the program as administrator, disabling any potential antivirus, and if both of those fail, good old Google since it's a fairly common issue.
If those don't work, please let me know and I'll see if I can find another solution! Usually it's just being blocked by a defense program though.
