Sadly this did not work. I've tried a few other things and here were my findings.
1. Tried that link and fiddled with compatibility mode trying windows 7, vista and 95.
2. Tried what the forum post says which is to give 'unrestricted access' but there is no option like that in properties, I am the admin and I already have all the access I can see.
No difference noted. I did some more digging and found that when I launch I can see the app open in task manager briefly and then closes. Sometimes it also has another program that opens briefly before it closes called WerFault.exe.
Looked into WerFault.exe and found indications to look into the reliability monitor on windows where I can see windows is logging errors when ever it's tried to open. Followed that down and the suggestions were to run sfc, disable windows defender (a common suggestion) and more.
I tried running SFC, disabled windows defender as much as windows will allow me to and tried all the above again (compability mode etc). No dice. I also looked at the printout of the reli monitor to see if the web had anything but no dice.
I think that I'm stuck and also scratching my head. I'm really not certain as to why it simply won't open as I have not seen this on other apps or itch.io games.
For now I'm out of ideas and have nothing else to try and it's probably not a priority given I've seen no one else having this issue. However if you decide you wish to investigate then let me know and I can provide any diagnostic material you want.
