What Is the 0x8007045d Error and Why Does it Occur?

This error tends to appear when trying to copy or delete files from an external source such as a flash drive or CD/DVD to your computer. Alternatively, you may be trying to install an app. When this problem occurs, you will get a dialog box that says:

  • “Error 0x08007045d: The request could not be performed because of an I/O device error (0x8007045d) Please rerun the backup once the issue is resolved.”
  • “Windows cannot install the required files. Make sure all files required for installation are available and restart the installation. Error code: 0x8007045d.”

This issue typically manifests when your computer has difficulty locating or reading specific files. It usually appears following a program or OS update. At the same time, this problem can also be caused by corruption of the Windows registry, system or application files, file downloads, memory modules, or storage devices (external hard drive, USB drive, CD, or DVD).

Preliminary Fixes

Many issues can be easily resolved by upgrading to the most recent version of Windows. Installing the most recent Windows update has the potential to resolve the 0x8007045d error message, so make sure you do that before proceeding to the next fixes.

You should also restart your PC before going forward. Often, all it takes to resolve a minor system problem is a good old system reboot.

1. Download the Affected Files Again

If the 0x8007045d error message popped up as you’re attempting to open a downloaded file, it’s possible that something went wrong during the download, leaving you with a corrupted or incomplete file.

In this case, you may want to remove the partial files from your computer and download them again from the source before trying to install or copy them again. Comparing the downloaded file size with the size on the official website is a quick and simple way to ensure that the file on your PC is complete.

Ensure that it is securely inserted into the USB port. You can either remove it or place it in another slot.

The Windows Registry is a core database that maintains all of the system’s configuration settings, user preferences, file properties, and other critical data.

6. Clean Your CD/DVD

Grimy fingerprints on the disk can be another reason you’re getting the 0x8007045d error. If your disk isn’t clean, your computer’s disk drive may have difficulty reading the data on it. After thoroughly cleaning the disk, try reading it again.

The error message can also appear if your CD or DVD suffers from damage, such as cracks or scratches. For shallow scratches, you can try to fix those using a repair software such as CD Repair Toolbox.

There’s also the toothpaste method, which involves putting regular toothpaste on the CD’s shiny side, where the scratches are the most obvious. You’ll need to distribute the toothpaste evenly with your finger or a microfiber cloth. Next, clean the disc with a different and wet microfiber cloth. Finally dry the CD using a dry microfiber cloth in a circular motion.

If these methods fail, you can try getting your CD/DVD fixed by a professional at a repair shop.
