I've been trying to install 2019.2.0f1 all evening. When installing through the hub, the progress bar reaches the end, then begins the 'cycling' while saying 'Installing'. But it never ends. And checking the properties of the install folder, it just keeps getting bigger. I had to end the task to stop the cycle, then manually delete the install folder, which was over 8 gigs! I uninstalled and reinstalled Hub - no change. I'm on Win7 - never had this issue before today... *EDIT: The folder '2019.2.0f1\Editor\Data\PlaybackEngines' alone is 6 Gigs.
