Archos Arnova Android 4 Tablets can run Google Play
When first using the Android 4 Tablet you will probably need to update the firmware to enable Google Play Store to run properly.
From your download app program search for ArcTools and install. Once installed run the ArcTools App and in the menu bar at the top you will see the Firmware Update option.
Run the Firmware Update making sure that you are either charging from the mains or from USB.
Once updated the Tablet will restart and once reconfigured will run Google Play
