Hey Kokopod, I had a similar problem and got it to run; here's what I did. I deleted everything (the .zip file and the Stardew Valley icon with the chicken), and then I did steps 1-5 of the wrapper preparation. Accept and install whatever pops up (I don't remember if anything pops up for that step). Do not close out of the window that runs those files. Then select and run only msxml3. It should open a Finder window (don't close it) and send you to a website to download a file. Download the file, then open a new Finder window (by right clicking on Finder) and move that file from "Downloads" to the folder it opened up for you (if it doesn't open it up for you, look through these forums; I think someone posted how to command that folder to open up). Then run it again; if anything pops up, install it (I don't remember if anything pops up when you hit run again). Finally, run it AGAIN. And it should say something about skipping it because it already downloaded it (or some similar phrase). Then select and run only dotnet40 next; accept and install whatever pops up. Run it again, and it should say something about skipping it because it already downloaded it. Then select and run only xna40; accept and install whatever pops up. I vaguely remember this one being the one that takes longer to install? Anyway, run it again, and it might have you install something else. I think it said something about skipping it because it already downloaded it the third time I ran it. Then start the "To install using Steam" instructions. When you hit "play," it finally should have error messages for you. Hit "Ok" for the first one, and then install whatever it tells you to. I think it was the xna installer thing again. I don't remember if it didn't play after working through the error and installer, but it certainly worked the second time I hit play. Tl;dr: always accept and install whatever it tells you to; run msxml3 first on its own, then run dotnet40 on its own, then run xna40 on its own; and check that those ones are installed by running them until it says they skipped it because it's already downloaded it. I hope this helps, but if it doesn't, I can't help you beyond what I just told you. Someone with more technological expertise will have to help you if you don't have the exact same problem I did lol. Good luck!
