I am running Windows 8.1 and am trying to download Windows 10 for installation on another machine. I have a brand new 4GB SanDisk Cruzer Blade USB drive that has been formatted.
In the Media Creation Tool, I select the options I want, Create installation media for another PC, English (US), Windows 10 Pro, 64 bit, USB flash drive. On the Select a USB flash drive step, I get the message "We can't find a USB flash drive".
I have tried the front and rear ports of the PC, formatted FAT32, formatted NTFS, quick and full format. Device properties shows Disk drive on USB Mass Storage Device. Drive is the default Windows driver, 6.3.9600.16384, 6/21/2006.
