Hello,

The version of Vuforia in a given version of the Unity Editor is static. For example, Unity Editor 2018.3.3 is released with Vuforia 7.2. If Vuforia updates the SDK to 7.5, the version of Vuforia in the Unity Editor 2018.3.3 is not updated to 7.5.

To upgrade the version of Vuforia embedded in the Unity Editor, please follow these steps:

1. Open the Unity Editor
2. Select Window->Vuforia Configuration
   • If there is an error message about Vuforia not being enabled, please follow the instructions and restart this process
3. If your version of Unity is eligible for a Vuforia update, you'll see a message and link to download the installer
4. Download and extract installer executable from downloaded ZIP file
5. Quit Unity Editor
6. Run the installer executable
   • For Windows, select the folder that corresponds to the installed version of the Unity Editor that is eligible for the Vuforia update. Ex: C:\Program Files\Unity_2018.1.4f1
   • For Mac, select the drive
     • If the Unity installation you're upgrading
       • IS NOT in /Applications/Unity/, select "Customize" and change the Location to the desired folder
       • IS in /Applications/Unity/, select "Install" to complete the installation
7. Restart the same version of the Unity Editor in Step #1
8. Verify the update in the Unity Editor via Window->Vuforia Configuration

If you have any previously installed Vuforia samples, you'll also want to download the updated versions of those from the Asset Store.

Thanks,

This worked perfectly, thanks!

Hello @lwarner,

This sounds like Vuforia Augmented Reality Support has not been enabled in your project: Unity Editor->File->Build Settings...->Player Settings...->XR Settings

Thanks,

Hi, This problem is still persistent. Has there been anyone addressing it. Vuforia Support?

Edit: In more detail. When I build for android, its fine when I build for IOS I get a stream of issues. 

error CS0246: The type or namespace name 'ModelTargetBehaviour' could not be found (are you missing a using directive or an assembly reference?)

error CS0246: The type or namespace name 'ModelRecoBehaviour' could not be found (are you missing a using directive or an assembly reference?)

error CS0246: The type or namespace name 'Vuforia' could not be found (are you missing a using directive or an assembly reference?)

Hello,

Disappointing to hear that the error persists.

This sounds familiar to similar reports on Mac OS, which may be related to user permissions (an account with admin privileges has to install Vuforia for the update to be recognized). Suggest you use an admin account for installing.

Thanks,

Thank you so much for your answer!

I followed your instructions step by step (which is, exactly how I used to do it previously), and the problem unfortunately still persists. Let me break down the steps I did:

- Installed Unity with the Vuforia plugin included in the Unity installer. With Unity 2018.2.14f1 it's Vuforia 7.5.20.

- Verified that Vuforia is installed by loading a project that uses Vuforia. Built and tested an application, it works.

- Opened Window/Vuforia Configuration.

- Under Global I got the following message: "A new version of Vuforia is available: 8.0.10 [...]"

- I clicked the link titled "Download Vuforia 8.0.10." and downloaded the installer. ("VuforiaSupportInstaller-Windows-8-0-10.zip", it contains "UnitySetup-Vuforia-AR-Support-for-Editor-2018.2-2018.3.exe")

- Ran the installer and selected the correct path to the Unity editor.

- The installer finished without any problems. (The contents of the previously mentioned "[...]/PlaybackEngines/VuforiaSupport/" folder got updated.)

- Ran Unity again: Vuforia installation is not recognized: no Vuforia submenus are found (i.e. no Window/Vuforia Configuration, etc), the previously working project won't compile/build/run, missing the Vuforia namespace.

Any help would be greatly appreciated!
