WU_E_PT_ECP_FAILURE_TO_EXTRACT_DIGEST
WU_E_PT_ECP_FAILURE_TO_EXTRACT_DIGEST means the processor could not retrieve the digest needed to validate an external CAB file. The CAB may be incomplete, malformed, or inconsistent with the expected content.
What to check
- Look for an earlier download, decompression, or content-location error for the same CAB.
- Reacquire the content from the intended service and check the server-side content store for corruption.
- Do not bypass integrity validation to force installation; the digest check is the evidence that the payload is trustworthy.
