If it's a zip, open it and extract it. After u extracted it, go to Google and search up "gamehub". Click the first link (I think) and download it. When u enter gamehub create an account. Go to the windows logo and click "import PC game". Go to downloads and then go to the file u extracted before. Right after that, click on the yandroid simulator exe (if it's an exe). If this doesn't work, then download Zarchive and find a tutorial on YouTube how to download a apk if it's a zip. Hope this helps <3
