--- Comment #1 from Louis Lenders  ---
Confirming. Guess it`s due to:

006c:fixme:mountmgr:harddisk_ioctl Unsupported ioctl 2d0c14 (device=2d access=0
func=305 method=0)
DeviceIoControl() failed with 0 bytes returned.  [234]
Exception when enumerating drives:
System.Exception: Exception of type 'System.Exception' was thrown.
   at Daybreak.Win32.Kernel.IsInternal(DriveInfo driveInfo)
   at Dawn.InstallLocations.Scan(Int64 requiredSpace)
CreateFileW(\.\E:) failed.  [234]

With the stupid hack below I was able to get it around it and it starts
download stuff; I stopped it for now as it`s a 5 Gb download..

hack:
