Hello.

I face the same issue for few months. I tried several times to upgrade to Vuforia 8 in Unity, but it keeps failing.

I follow the exact steps you mentioned but with no success. I cant' pass the Installation.

Please, we need help in this matter.

Hello,

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. Run the installer executeable
   • 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
     • Note that for Mac, the installer executable will default to /Applications/Unity. This is a limitation of the Unity installer scripts. If you have multiple Unity application directories in this path, rename the target Editor version temporarily to /Applications/Unity to complete the installation
6. Restart the same version of the Unity Editor in Step #1
7. 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,

Vuforia Engine Support
