How do you upgrade the new version of Vuforia, I dont understand any previous threads; I receive this message when i open Unity;
This sample is not compatible with Vuforia SDK version 8.0. A newer version of the SDK (8.1.7) is available.
Do I need to delete Vuforia and add again.
When I try and install by clicking on the new software it says there is an error installing.
Thank you so much in advance :)
