Follow the steps to configuring Apps for SharePoint 2013
- Create Domain (Forward Lookup Zone) example apps.systemsltd.local #Source
- Configure App URL #Source
- Manage App Catalog
Here you’ll be creating site for Apps
- Now you’ll be able to add an app. Make sure you’re not logged in as System Account and the user who is adding App from App Store is in Local Administrator account (without it I was having error).
