However, during the process of transferring the file to the USB drive, the error 0x80070456 – 0xA0019 may show up on the screen and interrupt the process. This error always comes along with the message: There was a problem running this tool we’re not sure what happened, but we’re unable to run this tool on your PC.
Once you run into this annoying error, you need to take immediate actions to fix it. In this post, we summarize several feasible solutions. You can have a try.
Solution 1: Convert the USB Drive to MBR
If your Windows only supports Legacy boot mode, you may encounter the error code 0x80070456 – 0xA0019 while installing Windows with a GPT USB drive. In this case, you have to convert your USB drive to MBR. Here’re two ways to execute the operation.
Way 1: Use Diskpart

Step 2: Type cmd in the dialog box and press Enter to open Command Prompt.
Step 3: In the panel, type the following commands and press Enter after each one:
- list disk

Way 2: Use MiniTool Partition Wizard
If you are not similar to the commands in diskpart, we recommend you to use a piece of third-party software – MiniTool Partition Wizard. It is a comprehensive partition manager that also enables you to convert a disk to MBR/GPT. What’s more, the conversion is simple and won’t lead to data loss.

The file system of the USB drive for the Media Creation Tool is FAT32. Therefore, if you use an NTFS drive, you are likely to run into the error code 0x80070456 – 0xA0019. To resolve the error, you ought to format the USB drive to FAT32.
Here, we summarize three methods for you.

Solution 3: Make Sure Enough Space in the USB Drive

Therefore, to get rid of the annoying error, we recommend using a blank USB flash drive with 8GB of space or larger.
If there are some files on your USB drive, they will be deleted during the process. So, you need to make a backup first to avoid data loss.

Step 2: Locate the mediacreationtool.exe file. Then right-click this file and select Properties.
Step 3: Go to the Compatibility tab. Then tick the checkbox next to Run this program as an administrator.
Step 4: Click Apply and OK to save the changes.
After that, try the operation you failed before to see if the error is resolved.
Solution 5: Temporarily Disable Antivirus
The third-party antivirus you have installed on your PC may recognize Media Creation Tool as a threat and interfere with the process while this tool is running. As a result, you may receive the “there was a problem running this tool we’re not sure what happened” error message. As for this, you should try temporarily disabling antivirus software to avoid this annoying error.
Any virus or malware may attack your Windows system after the antivirus software is disabled. So, you need to enable antivirus as soon as you fix the error code 0x80070456-0xA0019.
