Issue

When you install the K2 for SharePoint app in an upgraded K2 environment after removing a previous version of it, the following error occurs:

Sorry, something went wrong. A different version of this App is already installed with the same version number. You need to delete the app from the site and the site recycle bin to install this version.

Cause
