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:

    This is ridiculous. Just like all of you, I just want the tools to work. Is it really too much for one of the richest companies in the world?

    Trying over and over again (whether is it with this tool - in my case the third time wasn't lucky, maybe the forth will be - or with other solutions) is simply a waste of time and a lot of unnecessary stress for an IT newbie like me (I don't understand a half of the posts in this threat and I do believe that there are people out there who understand even less).

    The first line of the error allert is apparently the best conclusion: Microsoft is not sure what happened.

    I just want the tools to work. Okay, they can not work from time to time - after all only people create them. But when they don't work, it would be nice from Microsoft (or whatever company is it) to make a statement: why they don't work and how to make them work.

    Thousands of people have this problem (not everybody ticks the option or even reads this thread), two weeks have passed and Microsoft is still... not sure what happened.

    Well, this is what happens when there is a monopolist with virtually no authority that has control over it.

    But this isn't new. I've had this issue for about 2 years. Maybe one thing I'm doing different is that I tell the tool to make me a USB drive with BOTH 32 and 64 bit versions. Maybe 99.9% of the people don't do this.

    You can download the ISO file through Media Creation Tool though, right?
