If you can't install Android apps by browser, you can install apps by Play Store

After reinstalling Android x86, some apps can't be installed by visit play.google.com in browser, there's a button with the text Installed and green background, after click that button I can't install app.

In this situation I gotta give up installing apps via browser, but use the built-in Play Store to install apps. In the built-in Play Store you click search button at top right to search for applications you ever installed.
