What does Windows error code 14109 (ERROR_GENERIC_COMMAND_FAILED) mean?

ERROR_GENERIC_COMMAND_FAILED

A generic command executable returned a result that indicates failure.

ERROR_GENERIC_COMMAND_FAILED is Win32 error 14109 (0x0000371D) in Windows side-by-side assembly, setup, localization, and servicing infrastructure.

Likely impact: HTTP or wrapper success does not override the child process exit status, and partial external effects may remain.

Typical causes

• the executable returns nonzero.
• the command line or working directory is wrong.
• required environment or privileges are absent.
• the process is terminated or times out.

Troubleshooting steps

1. Verify that the process starts, completes within policy, and returns an exit status accepted by the caller.
2. Collect resolved executable and command line and working directory and environment.
3. Match the child process exit code or termination reason with its stdout and stderr, then compare that value with the success codes accepted by the caller.

Useful evidence

• Collect stdout and stderr.
• Collect servicing transaction and side effects.

Recovery and retry

Run the exact command in a controlled diagnostic context, fix its specific failure, and let the owning setup engine perform the retry.

Related errors

ERROR_CREATE_FAILED can mean process or object creation failed; this code means the command ran far enough to return a failing result

Example

A servicing command launches successfully but returns an application-defined exit code after failing to find an input file. Capturing stderr reveals the missing path.
