Error: "Database could not be loaded and cannot be activated" !!

April 1, 2020 - 10:39am #1

Hello all , 

I tried to create a basic Image target with device database i created.

I got errors like : "Could not deactivate dataset", and "Dataset ____could not be loaded and cannot be activated"

https://developer.vuforia.com/sites/default/files/%E2%80%8F%E2%80%8F%D7%9C%D7%9B%D7%99%D7%93%D7%94.PNG



It seems like this error was mentioned here several times and none of the users got detailed answer about it

I am using Unity 2019.3.7f1 but also tried unsuccessfully on 2017.4.38f1. (with Windows)

My vuforia version is 9.0.12.

I followed after a few tutorials like : https://www.youtube.com/watch?v=Wqbg9mB84V4 and https://blogs.sap.com/2019/05/15/my-first-experiment-with-augmented-realityar/

(Yes , i rememberd to check these (https://developer.vuforia.com/sites/default/files/%E2%80%8F%E2%80%8F%D7%9C%D7%9B%D7%99%D7%93%D7%941.PNG) checkbox on 2017 unity version)



I have already tried the following: (on both unity versions)

- Remporting all

- Downloaded the database a few times 

- Changed a license key (i got a developer license key)

- downloaded a sample project and tried to play it too - got the same problem (i have downloaded the project from https://www.youtube.com/watch?v=Wqbg9mB84V4)



This is how my ImageTarget Inspector looks like :

This is how my hierarchy looks like:

Hi,

The video is a little bit old and a lot has changed with Vuforia.

My recommendation would be to:

1. Use the latest release, 9.0.12

2. Download the Core Sample app from the Asset Store

3. Add in this project your own Image Target db

The Core Sample project contains a demo with all our features.

Thank you.
