PRB: "CRC Error" Occurs During Setup

ID: Q105595

The information in this article applies to:

  • Microsoft FoxPro for MS-DOS, versions 1.02, 2.0, 2.5x
  • Microsoft FoxBASE+ for MS-DOS, version 2.1


A "CRC Error" message (MS-DOS extended error 23: "Data Error - (CRC)") occurs during installation of FoxPro or FoxBASE+.


When reading a disk, MS-DOS performs a cyclical redundancy check (CRC) to verify disk sectors. The CRC is a sophisticated parity check of the data in each sector and will detect most data errors, such as lost or scrambled bits.


To determine if there is a problem with the disks:

  1. Attempt the installation a second time.
  2. Install on a "clean" (minimal) configuration.
  3. Install on another machine to verify there is not a hardware problem.
  4. Copy the floppy disks to a temporary directory on the hard disk and run the Setup program from this temporary directory.

If the installation still fails, call Microsoft Technical Support for assistance. Additional query words: FoxDos 2.50 2.50a 2.50b errmsg
