So I'm assuming the game is downloaded and ready to play! Make a shortcut on your desktop (is easier for the next part). Right click and go to properties (I'm sure it's properties I'm on my phone right now). There should be an option under one of the tabs that allows you to choose a compatibility mode. Like: compatible with windows 8 or compatible with windows xP . It allows you to change it so the file will run thinking it's on that windows system. I hope that helps!
Google how to fix the administration part (you probably have to do cmd things but don't take my word for it).
I did that once and it took me 15-20 mins to fix it.
When you ARE able to mess with it again, move the folder to a different folder (I move mine to a game folder you can also just make one on your desktop), do NOT open the zipped folder, you don't have to select the files one by one, just simply right click and extract all. It probably thought you were trying to open it while it was in the zipped folder. You don't have to open to folder to extract. You just click it once to select, and right click. It'll give you a list of options and it should say around the top: extract here. It'll just make another folder with all the files in it.
I'm not sure which program you're using or how you're extracting it, but I suggest a right click and: extract here on the zip folder, if you're able to.
Instead of opening the folder and doing it there.
I hope this helps. If you're doing it that way then I'm sorry.
I decided to push on to see if it was just that one pokecenter. I made it through the routes and the forest, then I went to the NEXT town's pokecenter. I tried to heal my pokemon and it crashed showing this:
