Recently while trying to deploy an SharePoint 2013 App, I got the below error:
Error occurred in deployment step ‘Install app for SharePoint': The provided App differs from another App with the same version and product ID.
Also check out:
The error is coming because an app has already been deployed and you are deploying it again using the same version. So the solution is to change the version.
Open the AppManifest.xml file and change the version.
Suppose the version previously was 22.214.171.124, you can change that to 126.96.36.199 and it should work fine.
