Hello, can you specify more what happened? Black screen? Did you open the right .exe file? :0c
actually, I have a similar problem. It's not downloaded as an app for some reason so it's just Homegrownpet.rar
like what Foxyloxy said, I downloaded it and it won't open. If it helps I did click install. When I double click to open it, it asks to open it with a certain app. (also im on a windows 11 or 10)
