I have created an app using VS2013's convert to SharePoint feature. I have tried adding the app in two ways namely Provider hosted and SharePoint hosted, both of which return an error.
I want the app to be internal so I believe it needs to be SharePoint hosted which returns the following error in Visual Studio:
Error occurred in deployment step 'install app for SharePoint': There were errors when validating the App Package
Alternatively, when the app is Provider hosted I can upload it to SharePoint but I get the following error when I try to add it:
The specified application identifier * is invalid or does not exist
Does anyone know how I can solve either of these issues?
Cheers for any help
