Setup cannot access a needed file

Setup is not able to access a file that it must use to install your software.

Possible causes of this issue include the following:

• The CD or DVD is dirty   The disc might have dust, smudges, or fingerprints on it. Cleaning the disc usually resolves this. You can clean the disc with any commercially available cleaning kit. Follow the disc manufacturer's recommendations. Use a soft, lint-free cloth, and wipe gently in a straight line from the center of the disc to the outside edge. Always handle the disc by its edges, and always avoid touching the shiny surface of the disc.
• The CD or DVD is damaged   The disc might be physically scratched or in some other way damaged. If so, you must either repair the disc or order a replacement disc from Microsoft Product Support.

  When a disc is scratched, a scratch in the clear coating of the disc interferes with the laser that reads the data — the disc's data section itself is not damaged. You can repair the disc either by filling in the scratch with an optical material or by polishing down the scratch to remove it. In either case, follow the disc manufacturer's recommendations. There are many commercial products that are designed to help you remove scratches and dirt from a disc.

• The CD or DVD drive does not work   Your hardware might be damaged, or it might need an updated driver. It is always a good idea to download the most recent software updates both from the computer's manufacturer and from Microsoft Update.

Test the disc and disc drive for problems

To establish whether there is a problem with the disc or the disc drive, do the following:

1. Insert the disc into the appropriate disc drive.
2. Click Start, and then in the Start Search box, type Run.
3. Under Programs, click Run.
4. In the Run box, type cmd, and then click OK.
5. Working in the Command Prompt window, change to the disc drive (typically drive E).

   To do so, type the drive letter and a colon — that is, if the disc drive is drive E, type e: — and then press ENTER.

6. Type dir /s (making sure to include a space before the slash), and then press ENTER.

   This command displays files in the specified directory and all of its subdirectories.
