Facing the below error while Creating an App in SharePoint 2

You could try fixing your setup by closing Visual Studio and then following steps:

1. Go to Control Panel > Uninstall a program
2. Select Microsoft Office Developer Tools for Visual Studio 2012 - Preview 2 - ENU
3. Click on Change to uninstall it. The setup program should launch.
4. Click on Uninstall to remove the Office Developer Tools.
5. Download the Office Developer Tools using this Web Platform Installer link. This Web Platform Installer should install the Office Developer Tools and all the prerequisites (Exchange Web Services, LightSwitch HTML Client, etc).
6. Try creating your SharePoint 2013 Empty Project again.

Please Mark it as Answer. If it helps you. Thanks in advance.
