HDP on Windows – Installation Forum

Uninstall failed, manual deleating

    As my my uninstall was failing, I deleted all the relevant folders, logs and registry entries. However now install still says, ‘Please uninstall current HDP installation before installing HDP’. Is there a patch to do manual or force clean up all the entries, so that fresh install gets through.

    In all HDP Windows is still in very premature state. Would be glad to see this improve by leaps.

    Any support for this please.. I tried to clean every where I am aware of in windows, it still says uninstall HDP..

    Where all I need to delete things manually so that I can do fresh install or is it possible for HDP windows msi to force re-install/repair.


    Hi Raja,

    It appears that you now have an inconsistent installation due to the manual removal of directories.
    I would suggest cleaning the registry keys – as this is where the installer is looking to check for the HDP installation.
    You can use regedit to search the registry for HDP and remove the keys.
    The uninstallation on windows is usually very good if you install / uninstall as administrator.

    Hi Dave,

    Can you pl. let me know the list of registry entries to remove.. I did remove all the entries but it still saying the same thing.. i.e ‘Please uninstall current HDP installation before installing HDP’.

    Finally got this working, searched in registry (regedit) for ‘hdp’ and deleted all relevant entries..
