Nonexistent playback engine directory

This happened after I downloaded Unity 5.1.2f1 and implemented Unity Analytics.

Here is the error message:

“Can’t set nonexistent playback engine directory ‘C:\Users\Lord_Ford\Documents\Editor\Data\PlaybackEngines\wp8support’
UnityEditor.Modules.ModuleManager:Initialize()”

-Thanks

You need Install the new unity into the old folder
