Begining Vuforia Engine 7.1 and Unity 2017.1, Vuforia provides custom update installers that can be used to patch your existing version of Vuforia Engine within Unity. Update installers are similar to Unity’s component installers and will be provided for important updates to the Vuforia Engine. In addition, developers enrolled in Vuforia’s Early Access Program (EAP) will receive early updates to the Vuforia Engine via Update Installers.
Update Installers for the Vuforia Early Access Program
If you have access to a Vuforia EAP, Update Installers will be made available for developers to download in the Vuforia developer portal. Update Installers will be made available for specific versions of Unity. Please be sure to download the appropriate version of the EAP corresponding to your version of Unity. Not all versions of Unity will be supported by all EAP releases.
