I tend to install most apps on my D drive as the C drive is an SSD. On release 3291, the install has hung on both my desktop and the laptop when changing the install directory to D. I aborted the install several times on each after a minute or so.
Browsing to the folder did not work.
Changing C: to D:, going to the end of the line then hitting return did not work.
Changing the C: to D: and then clicking install did work after a delay.
The second part of this is that the install did not honor the Win 10 setting of where to install new apps.
Win 10 Pro, versions 1809, latest updates installed.
