Try another USB port. If everything works fine with another port, then you will probably need to fix your other USB port.
If the error occurs when you use a CD or DVD, clean the disks and try again. When disks are dirty, the disk drive may not be able to read it properly. If the disks are damaged (for example, scratched), then try to repair them.
If you are installing an update or an app from an external disk, copy the files you need to your computer and run the installation from it. Another option is to send your files to your computer via a cloud service or email.
If you are installing files from the Internet, and the error pop-ups, maybe the files are corrupted. Stop the download and try again.
