The post you have mentioned was originally a question about troubleshooting installation but eventually led to different problem.
This post is about license.bin file not being present in the 8.1 version.
I received a response from support team today. They said that 8.1 version had issues, so they removed 8.1 version and replaced it with 8.0 version.
I will post further updates if I get the same issue.
Thank you for your response.
