Ways to solve Windows error code 0x8007045d

There are some simple fixes that you can apply to rid your Windows PC of error 0x8007045d.

Restart the computer

The simplest fix that you can apply is to restart your computer. Reboots often fix minor issues with your system, including error 0x8007045d, allowing you to resume whatever you were doing without any issues.

It’s easy to restart both Windows 10 and Windows 11 computers. When your device restarts, perform your actions, and your problem should be resolved.

Update your computer

Check the connections of the hard drive, USB drive, and CD/DVD drive

If you encounter error 0x8007045d while trying to access files on an external drive or disk, check to ensure that your computer’s connection to this device is not loose.

Windows cannot read or copy files from a loosely or incorrectly connected device. Check your device’s USB port or CD/DVD drive and make sure it is working properly. You can try swapping the USB device port to see if that fixes the problem.

If the drive you’re managing files with is built into your machine, a bad connection is less likely and more of a challenge to identify and fix (especially in a laptop).

Update your device drivers

Your USB or CD/DVD reader drivers may be out of date, causing these devices to not work properly with your computer. In this case, you will encounter error code 0x8007045d while trying to read or copy files stored on these items.

Copy your files to your computer

If you are getting the error “The request could not be executed due to an I/O device error” while trying to install a program from an external storage device, first copy the files of that program to your computer’s local storage and then run the installer. This will ensure that the connection problem does not prevent you from installing your app.

Redownload your files

When error code 0x8007045d appears for a file that you downloaded from the internet, there is a good chance that the file is corrupt. There are many reasons for this to happen, with an intermittent download process being a common culprit.
