    Hi Ryan,

    I have not tested it yet so I am not sure if it will work or cause more issues, but you can try removing HDP from registry manually. Here is some information:

    I was able to locate record in registry by searching for “hortonworks” and locating record in …\uninstall folder in registry.

    Please let me know if this is useful.
