installing a test app on windows 8.1

[sam_w_1]

I'm having trouble installing a test app on a microsoft surface running windows 8.1. I managed to install a test on windows 8, then upgraded to windows 8.1. When I try to run the ps1 file in powershell, I get an error about a package already being installed - but I can't work out why this is or how to resolve it. Error log is attached - if anyone has suggestion would be much appreciated!

Sam.

Hello,

Try uninstalling the app and  install it again.

It means that a package with the same App ID is already install on your device. You either have to delete that existing package or change the app ID in your new installation. 

You can change the app ID from the Project tab -> Build Settings -> Windows 8 -> App ID (first field).
