ERROR_CRC while upgrading the OS to Vista Home Edition

Hi there,

I have read about the error ERROR_CRC (0X80070017) coming on your computer.

I have two solutions for you against the problem you have or if in case the problem will exist again you can still use the same steps for troubleshooting.

The first one is very simple, to check the disk for error by using Chkddsk.exe tool. Follow the below steps.

• Click the Start button.
• Look for Start Search bar right above the start button.
• Type cmd in the search bar and then it will search for this program automatically while you're there.
• At the top of the program you will see a black icon that says command prompt.
• Right-click the black icon in the Programs list.
• Click Run as administrator.
• If you will be prompted for an administrator password or confirmation then type your password and click on continue.
• A black screen will load up, on that screen type in: Chkdsk /f and Hit ENTER.
• Press Y when you are prompted to check the disk next time that the system restarts.
• Close all applications, and then restart the computer. While the computer restarts, windows begin checking for the disk errors.  After the computer has restarted, install the updates again.

Second Solution is:

• Click the Start button.
• Look for Start Search bar right above the start button.
• Type notepad. And Hit ENTER.
• Copy and paste the following commands on the notepad:
  • net stop wuauserv
  • CD %systemroot%SoftwareDistribution
  • Ren Download Download.old
  • net start wuauserv
• Click File menu at the upper left side of the screen and then Click Save as.
• In the File name box, type rename.bat and then click All Files in the Save as type box.
• Save the file to the desktop so you can easily see it.
• Look at your desktop for the file and then Right-click the rename.bat file.
• Click Run as administrator.
• If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
• And Try to install updates again.
• If you're installing, you can delete the file rename.bat.

Hope these solutions are helpful for you.

ERROR_CRC while upgrading the OS to Vista Home Edition

If you are receiving a “CRC” error when installing, it means the installer you downloaded has a problem or contains corrupt files. This can happen if you downloaded the installer from a different site not from the official website. The problem happens as a result of modifying support files in the installer.

To make sure you are getting the original, unmodified version of the installer, download only from the official website. When a file has a CRC error, it means the file itself is already broken. CRC is the short term for “Cyclic Redundancy Check”. It is a method used to identify errors in digital data.

It is a hash function that detects unintentional changes to raw computer data normally used in digital telecommunications networks and storage devices like hard drives. In CRC, a constant number of check bits or frequently called a “checksum” is appended to the message that needs to be transmitted. The data receivers receive the data and examine the check bits for any errors.

Data receivers accurately verify the attached check value by finding the remainder of the polynomial division of the contents transmitted. If an error was identified, a negative acknowledgement is transmitted asking for data re-transmission. In your case, since the problem is triggered during installation, try downloading the installer again from a different website.

But if you are installing from a disc, try cleaning the lens of your optical drive with a CD/DVD lens cleaner. Also, try wiping the surface of the disc with a soft, microfiber cloth.
