Wikitude

Hello, i am using unity 2019.3.11 and Wikitude 8.3.0. I am trying to create an image tracker using "iot_tracker.wtc" included in the Wikitude Folder and nothing works. It show me this error, while i debug 

I have no idea, what should i do now. 

Having the same issue with 2018.3.6. Please help!

Hi, 
I was able to fix this issue by following this tutorial. Generating a licence key and changing the package name.
