Installation errors

Error 0x80070570

The file or directory is corrupted and unreadable.

Windows could not read the data it needed. The cause is either a damaged download or failing hardware, and telling them apart decides everything you do next.

What it actually means

This is a filesystem-level read failure rather than an installer problem. It appears during installation, extraction and Windows setup, and the file being read is only where the fault surfaced.

How to fix it, in order

Ordered by how often each one is the answer, not by how clever it sounds.

1. 01If it happened while installing downloaded software, re-download the file and verify its hash. A corrupted download is the most common and most easily fixed cause.
2. 02If it happened during Windows setup from a USB drive, recreate the installation media. Bad media is the usual culprit and the drive itself may be failing.
3. 03Run "chkdsk /f /r" on the drive involved. If it finds and repairs errors, treat that as a warning about the disk rather than a fix.
4. 04Test the RAM with Windows Memory Diagnostic. Memory errors corrupt data as it is written, so files fail verification for reasons the disk is not responsible for.
5. 05If it recurs across different files and different sources, the hardware is the problem. Back up before doing anything else.

Common questions

How do I fix error 0x80070570?

Re-download the file and verify its hash if it happened while installing software, or recreate the installation media if during Windows setup. Then run chkdsk and a memory test, because repeated occurrences point at failing hardware.
