Filter SDK .NET Programming Guide

# Error Codes

The following table describes various error codes that you might encounter while running File Content Extraction, and how to troubleshoot the problem.

Error | Troubleshooting steps
--- | ---
KVError_DLLNotFound | Check that no binaries are missing from the bin folder. Check the permissions on the binaries in the bin folder to ensure that the user running File Content Extraction has permission to read them. Check the software dependencies section. See Software Dependencies.
KVError_BadInputStream KVError_ReaderInitError | This error generally means that File Content Extraction cannot parse the input file and it might be corrupt. If the native application can open it, then create a ticket with OpenText support.
KVError_General | This error should not be seen in normal operations. Create a ticket with OpenText support.
KVError_PasswordProtected KVError_PasswordRequired KVError_RMSCredentialsRequired | This error means that the document is encrypted and the operation you are attempting cannot be performed without additional credentials. NOTE: If one operation requires credentials, it does not mean that all operations do.
KVError_CreateTempFileFailed | Check the temp directory configuration, and the permissions on the temp directory.
KVError_ChildTimeOut | See File Content Extraction hangs or stops responding.
KVError_PSTAccessFailed | This error usually indicates that you are trying to extract a PST by using the pstsr reader, which requires access to Microsoft Outlook. The pstxsr reader does not require that Microsoft Outlook is installed. If you prefer to use pstsr, see Outlook Personal Folders Files. If you do decide to continue using pstsr and are using 64-bit Filter SDK, also ensure that you have 64-bit Outlook installed. Similarly, 32-bit Filter SDK requires 32-bit Outlook.
KVError_InvalidLicense[BC1] [PB2] [BC3] | This error means that the license you provided is not valid, is valid only for an earlier version of File Content Extraction (KeyView), or does not allow the feature you are trying to use.
KVError_ExpiredLicense | This error means that your license is valid but has expired. Check that you are using your purchased license, rather than the trial license that is embedded in the sample and test programs. If your purchased license has expired, you must request a new one.
KVError_UnexpectedAppendedZip | This error indicates that the input file might be malicious. It might be two files concatenated in attempt to hide information.
KVError_ZipBombDetected | This error indicates the input file has an unrealistically high compression ratio and so might be malicious (a zip bomb). File Content Extraction has terminated processing of this file to prevent a Denial of Service.
