Thanks! I really appreciate that! Sorry for the late reply, went out of region for work. i'd love to help, I'm keeping track of the older versions as well, but for mac64! I am just eager to see what changes and how good is coming out! 

But thgis error is not new. I had it before with other, previous versions. Is it really just an uploading error, or is it a result of you using some specific settings during the process of building (compiling or whatever it's called) the game, the use of some specific version of the game engine, (I wouldn't be surprised if it would appear when you use the latest version of the engine to build the game) or  the use of some specific plugin that requires a more modern operating system or something... (I have every little knowledge in stuff like this, but, as far as I know, KERNEL32.dll is one of the most important and basic system libraries of Microsoft Windows family of PC operating systems, and the error message says: "Fallout Alpha.exe - Entry Point Not Found"

"The procedure entry point SetProcessMitigationPolicy could not be located in the dynamic link library KERNEL32.DLL" which makes me think that this should mean that this DLL is too old and doesn't have some of the required... I dunno... instructions? Whatever. In other words, it seems like this message basically translates as "your OS is too old, you need a more modern one with an up to date version of this core DLL that has all the required instructions or whatever". Are you sure you are not changing something OS specific settings, using some specific plugins or try different versions of the engine or something when you are building those builds that are giving me this error? Because the situation is repeating, and not the first time, so it seems like either Itch.io is "glitch.io", or there is something specific in those several versions that causes this problem. What have you changed to solve this issue it in the pervious times? I'm assuming that you have enabled something for legacy OS support when it happened before? Or what was causing this problem earlier? Or you've just tried to re-upload the same build again and it worked?
