Blue stacks is great! I have Play Store installed, and it force closes every time I open it; however, I've the log-on services framework installed. Maybe a few other things. I use blue stacks to access my existing play store apps I paid for, back them up using ES File Explorer, and upload onto google drive. I haven't had a problem installing and using paid for play store apps; play store closes, but it only really needs to be installed. It never lets me get past the terms of service agreement before closing.
Anyone getting past that without rooting? That kinda messes with the stock apps--considering I need those to work, rooting will never happen for my kfhd8.9.
