I get Error when Deploy that SharePoint App
Error 1 Error occurred in deployment step 'Install app for SharePoint': The System Account cannot perform this action.
Try it with another account other than the Admin account but with farm account similar privileges. The default admin account is treated as the system account and it will not allow apps to be added or removed via the system account.
Ideally, when setting up your environment, you should be using a system account (part of admin group) to login to the server but setup SharePoint using a farm account (farm admin and run all the app pools)
