I can not install apps from the SD card, when I try to install one it shows the message...

"we are having a trouble installing this app"

What can I do to fix this?

  • Where did you get the apps from?Is your phone set to the same region as the store you downloaded them from?

  • If you are using an account created with a different region, this could be part of the issue.

There are many reasons:

  • The developer of this app does not allow to install (or access) to SD Card.
  • Your SD card has error, try to reset it and install the app again.
  • If this app is developed by you and you deploy it from Visual Studio, I think that there is a problem about unlock your device.

I hope my answer can help you !

  • In addition to your answer , application installation will fail if there is more than one file in phone and any problem in internet connection ...
