I've recently updated to Vuforia 6.2 (Unity). After I've done everything in the update guide I got the following error:
Could not initialize the tracker.
I've tested this with an empty scene with just the ARCamera prefab from Vuforia in it: Same error message.
This happened in the unity editor with unity 5.5.0f3
Unfortunatly most of Vuforia is in an .dll and therefore I can't look into it myself.
in an additional test I integrated Vuforia in a new and empty unity project which resulted in no error message. So something must have gone wrong when I updated from my old version to the new. But I did everything I was told to do in the Migration guide.
So what specifically causes a "Could not initialize the tracker."
Thanks in advance
