This is a know issue that is very easy to miss. Usual indicationis if the web parts do not appear after deployment.
It usually means that the user used to launch the wizarddoes not have the access to the SharePoint database, so it’s recommended to usethe same user account that was SharePoint deployed to be used for Web Serverdeployment.
Also this issue happens when there is .NET4.5.1 installed in some configurations, please downgrade back to 4.0 .NET in order to be able to install the web parts correctly.
This issue is fixable by increasing the timeout value in SharePoint:
Configure Search timeo-out settings
This could be related to SharePoint app pool user change after the installation was already accomplished.This can be changed by manually changing BDC object access rights to a requireduser.
