I am running Unity 2018.1.0f2. First official 2018 release.
I have a Vuforia project which mostly works, but the components are telling me to upgrade to 7.1.34. It provides the link to download. I have done that.
From the zip was a setup file, which I run, which says "Setup will install Unity 2018.1 Vuforia AR Support in the following folder. To install in a different folder, click Browse and select another folder. Click Next to continue."
But the destination folder is empty. It won't continue until I select a folder. And I making up a folder to store it in and it said it was wrong. I have no idea what folder it wants.
Please note, I am using Windows and Unity Hub, which does not store Unity under the Program Files/Unity/ folder, but instead in Program Files/Unity/Hub/Editor under a named version folder, in this case 2018.1.0f2.
