Are you on a Chromebook? Google Play is only on Android devices or Chromebooks, which means you got the mobile version for free. If you buy the PC version it won't run on a Chromebook bc ChromeOS is different then Windows, and the PC version you buy here comes with all the hats.
This is always the mobile version. The emulator/OS you installed/were preinstalled on your PC is based on Android (the OS installed on most of the smartphones, I did the same with BlueStacks and it worked). The PC version is the one you can buy on Steam or itch.io
