Media Creation Tool Error 0x80042405 0xA001B

I must be doing something wrong because I always have the update fail with some BS error like this. What are the proper steps to run this tool?

I download the tool to the desktop. I'm on an Admin account. I insert a 16GB thumb drive. I format it. I start the tool. I point it to the thumb drive. During the phase where the files are copied to the USB, I get some stupid error like this:

Why are my steps not good enough? Where is the hole in my logic? Or is this tool just written poorly. I'd like to use stronger language here as I used to have to start it all over again and burn bandwidth trying this failed endeavor over and over.

I've heard people make it work by running the tool FROM the USB. Why would that matter? I've tried to write files to the thumb drive just after the format and before running the tool to make sure I have successful writes. Doesn't help. 

As a workaround today, I left the error up for a bit. Tried to access the thumb drive and it said it needed to be formatted AGAIN! So I did. Then I just opened the C:$Windows.~WS\Sources\Windows and copied the files to the drive by hand. Made the dang thing myself! WHO WRITES THIS STUFF??

Hello,

I would suggest you to create latest media. Download the Media Creation Tool using this link:

    Roy Beaulieu, 

    Perhaps MS fixed something on the latest MCT.  I'm on windows Pro x64 build 18362.267.

    The build of the latest installation media downloaded is build 18362.239.

    I tried another experiment that was reported as a possible cause for the error.

    I prepared a 16GB USB device with one volume in GPT instead of MBR.

    MCT downloaded the whole package again and when it was time to copy MCT reconverted to MBR,  reformatted the USB device as MBR FAT32 and copied everything over without any error. 

    Looks like I cannot make it fail even if I try on purpose. :(

    I have an out of town client who will be running the tool in the next 10 days. I'll have her just do everything by the numbers as a novice user and report back.

    Thanks for your testing and assistance. Would be nice if this nightmare is over.
