I have a Microsoft Lumia 640 Dual Sim, running Windows Phone 8.1. I accidentally uninstalled WhatsApp from the phone.
Now when I try to install it back from the store, i get an error asking me to try again later. The error code is
c101a7e3 . I can successfully download and install other apps.
I have tried a soft rest as well as made repeated attempts over the past 5 days, but to no avail. Is there a remedy short of a hard reset?
