 * width="100%"|

ID: Q90419

The information in this article applies to:


 * Microsoft FoxPro for MS-DOS, versions 1.0, 1.01, 1.02

SYMPTOMS
In FoxPro version 1.x for MS-DOS, an attempt to perform a database operation fails and the &quot;Missing or invalid RSC&quot; error message appears.

CAUSE
This error message appears under the following circumstances:


 * The user does not have the necessary network access rights to view the .RSC file.
 * The .RSC file has a different version date than the other system files.
 * The .RSC file is corrupt.

RESOLUTION
To resolve the problem, following these troubleshooting steps:


 * If the problem occurs on a network, log in as Supervisor. If the operation succeeds, network rights are not set correctly. Ensure that each user has search rights along the path.
 * Determine if more than one .RSC file is installed. Delete any additional copies of the .RSC file.
 * Make sure that each user issues SET EXCLUSIVE OFF before opening the database file.
 * On a peer-to-peer network, change the attributes of the FoxPro .RSC file to Read-Only.
 * If the steps above fail, reinstall FoxPro.

MORE INFORMATION
The FOXPRO.RSC file contains error messages and system messages that FoxPro 1.x uses. When an error occurs, FoxPro attempts to read the appropriate message from the file. If FoxPro cannot read the error message, it indicates an error on the .RSC file.
