Okay, I have made a detailed step by step guide on how to install it now! Please tell me whether it helped you!
First off sorry for the late reply had dr visits and physical therapy so i wasnt eble to check here for a while. thank you for the guide it ended up helping in a funny way, so the reason i gave up so quickly is because i actually went to college for interactive digital media i figured i at least remembered enough to be able to move a file, turns out i did but i forgot one simple thing that you mentioned in your guide. Check the file size mine was 3 gigs flat, it was corrupt just barely. I tried redownloading (still had some issues probably because my internets not great but it got 3.5gb after 3 tries) and it worked! I cant believe i forgot the most simple thing of just making sure it downloaded properly, i lost my saves as i had already deleted the app but i speed skiped to where i left off so thanks again. Hopefully your guide helps others and ill be coming back to it for updates just to get the app you used and archive my saves.
