My Nephew was able to install Google Chrome onto My Maxi Sys Elite, doing remotely and all through his PC after I opened Quick Support App , provided him the ID by phone and allowed remote control. I had work to do and an hour later checked and Google Chrome App was on the Android Home page and Works fine.
I asked how to do it. He Said " On your desktop, just search google for the app you want and find the link to it's google play store page, then copy and paste the play store app page URL into this website and click generate download link."
"Download the .apk file and put it in your downloads folder on your tablet."
"You should be able to tap the .apk file in ES Explorer,then tap install."
"You do it all on the PC, then use Team Viewer to transfer the .apk to the tablet. No usb stick required."
