Can anyone provide guidance on how to sideload BBM on to Windows 10 Mobile. I have downloaded the BBM .xap file from Then attempted to install it via the App Manager. When I try to deploy the file I get the error message "Failure reason: Missing .appx file name query parameter". Any help would be appreciated. For anyone questioning my sanity on installing BBM, I am migrating my wife to W10M, but only on the condition she has BBM to communicate with family overseas!

if you are trying to install windows phone 8.1 app it wont work as windows 10 phone uses appx as installer extension rather than xap as it were on windows phone 8.1 .Blackberry has not launched a windows 10 mobile app so i cant imagine of another way possible to sideload such an app
