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,

    Looks like everybody has some different remedy or workaround. I have the realtime protection on all the time and I can never make this thing fail....

    That's promising. I will give it a try on my next attempt. It makes no sense that the MS AV would not let writes to the thumb drive from the MCT. I can write and copy to it before and while the MCT is going.

    It's also possible that something else was the fix since people sometimes get success after 2, 3, or 4 tries while changing nothing.

    Hi I had this issue while trying to do a clean install for a friend. I simply just dragged the tool into my USB and installed it directly from there and it worked for me.
