During a Windows 8 deployment, the setupact.log within the Panther directory records installation phase errors. However, generic failure messages such as \"Failed to install driver package\" can occur regardless of whether the root cause is a missing dependency or a signature verification failure.
While error codes like 0x80070002 typically indicate a missing file and 0x800B0100 signals a driver signing problem, the Deployment-Services operational log in Event Viewer often mirrors the setupact entries while omitting verbose signature details unless the log level is manually adjusted.
It remains unclear whether increasing log verbosity via the <Debug>true&true element in the answer file is sufficient to capture the specific threshold for driver signing warnings, or if manual cross-referencing with the Code Integrity operational log is mandatory to distinguish these from package omissions.
The log that separates driver signing failures from missing package errors in a Windows 8 deployment is the SetupAPI.dev.log for signing issues and the DISM.log for missing packages.
windows8type %windir%\inf\setupapi.dev.log | findstr /i "0x800b0100" to locate signing failures.type %windir%\Logs\DISM\dism.log | findstr /i "0x80070002" to locate missing package errors.If your deployment uses a custom log path via an answer file or MDT/SCCM, verify those locations instead.

The Microsoft-Windows-CodeIntegrity/Operational log is the definitive source for driver signing failures, recording event IDs 3033 (signature validation failure) and 3034 (catalog file missing/invalid) that are absent from generic package‑error logs.
While SetupAPI.dev.log and DISM.log capture missing‑file or dependency errors (e.g., 0x80070002), they do not contain the Code Integrity‑specific IDs, even when Deployment‑Services logging is set to verbose via <Debug>true</Debug>. Therefore, to distinguish a 0x800B0100 signing error from a package omission, administrators should first check the Code Integrity log for those event IDs; if none appear, the same status code in SetupAPI or DISM indicates a missing package.
