It seems like you're encountering an issue with the Microsoft Windows Hardware Developer Program registration process. The error you're facing might be due to a mismatch between the signed "SignableFile.bin" and the original downloaded file.
To troubleshoot this, consider the following steps:
- Ensure File Consistency: Double-check that the "SignableFile.bin" you're uploading is indeed the same as the one you originally downloaded. Make sure there's no accidental alteration or modification during the signing process.
Checksum or Hash Comparison: Calculate the hash or checksum (such as MD5, SHA-1, or SHA-256) of both the downloaded and signed files. Compare these hashes to verify their integrity.
