When you deploy your app sometimes you can't update your app , some posts suggest to update the app version  from the AppManifest.XML file , unfortunately , It's not always working.

Quick fix for the problem is to update the app product ID using the following

  1. Open the AppManifest.xml
  2.  From the Tools menu open the create GUID tool
  3. Generate new GUID
  4. replace the product ID in the appManifest.xml file
now the app will be deployed with no errors.
