The DevSuite 1.4 installer failed while installing CDK. There are two problems

1. JBDS-3834 When an install fails and the installer can't make any progress, the flow stops. There is no prompt, no clues how to get help, find a log, etc. The user's only option is to give up and close the window.
2. JBDS-4272 the CDK install failed. It's not clear why, attaching /Applications/DevelopmentSuite/install.log. But looking at the logs it looks like there may be permission errors. There were no prompts related to needing to run as root, or password requests, etc. If it is permissions, it just silently fails.
3. JBDS-4441 Also, given that this is macOS, why is the installer trying to Windows admin commands (to add the user to "Hyper-V administrators")? (This should possibly be a separate bug.)
