I believe the non-GUI embedded SDK installer from 20-APR-2016 posted here [1] is corrupted, or at least the download keeps failing in the same way.
The SHA256 checksums do not match:
Posted [2]: 0c50d6d44db9cb030800cfffe0ff2a4d7022a2c1c5e0b9c9f2dc155435c5657a
Actual: d99df0557e8766d02036f583cca6fb95d066d7e7c7614f271c0b84efe711e81b
This error occurs when the script is self-extracting: [3]. Note that the GUI version downloads properly and has a correct SHA256 checksum.
Thanks,
Sean
