I got my Unity Version 2018.2.0f2 that I installed via the Unity Hub to work with a work around.
This issue with the Vuforia installer looked like a file path issue, so I copied my Unity installation directory to the directory it would have been if I did not use the Hub, installed Vuforia ‘UnitySetup-Vuforia-AR-Support-for-Editor-2018.1’ and then copied the new Unity directory back to my Unity Hub directory. My project opened and shows Vuforia 7.2.23
It is just a stupid error in the installation program… just use as destination folder C:\Program Files\Unity or wherever you have your unity installation folder… just forget about the \Editor and it will work
Then finally you wait, there’s no progress but there’s a indication of installing component on the place of the 3 dots, once it disappears it means component installed.
The workaround, as mentioned previously, is to set a folder to the parent folder of “Editor” folder.
For example, instead of selecting “C:/Program Files/Unity/Editor”, please select “C:/Program Files/Unity” EDIT: make sure Unity.exe is located inside folder named “Editor”.
Issue solved :
“C:\Program Files\Unity\Hub\Editor\2019.1.0f2\Editor” just remove the last “Editor” part and it should work fine.
Give file location like “C:\Program Files\Unity\Hub\Editor\2019.1.0f2”
