What does Windows error code 15152 (ERROR_PRI_MERGE_WRITE_FILE_FAILED) mean?

ERROR_PRI_MERGE_WRITE_FILE_FAILED

Unable to create the merged PRI file.

ERROR_PRI_MERGE_WRITE_FILE_FAILED is Windows status 15152 (0x00003B30) associated with creation or final write of the merged PRI output.

Likely impact: A partially written output must be deleted or quarantined and never published as a valid PRI.

Typical causes

• the output path is unwritable.
• the volume is full or quota constrained.
• antivirus or another process locks the destination.
• final serialization detects an internal inconsistency.

Troubleshooting steps

1. Verify that the destination can be created atomically with sufficient space, permissions, and a valid final index.
2. Collect output path and temporary path and free space and quota.
3. Correlate ACL and process token with MakePri command line, input PRI inventory, package identities, schemas, file hashes, output path, tool version, and the first detailed merge diagnostic.

Useful evidence

• Collect file sharing and lock owner.
• Collect MakePri finalization diagnostic.

Recovery and retry

Repair the destination and write to a fresh temporary file, then validate and atomically replace the intended output.

ERROR_PRI_MERGE_ADD_FILE_FAILED rejects an input during composition; this code fails while materializing the output

Example

A build agent can read every input but lacks write permission in the package staging directory. Correcting the directory ACL allows atomic output creation.
