    Hi @rajeeec-5608m,

    The error message shows ‘The 'OraOLEDB.Oracle.1' provider is not registered on the local machine’.

    I did some research online, please make sure you have already installed both 64-bit driver and 2-bit driver ODAC.

    Here is an article. for your reference:

    Below is the download link for you.

    You have to enter first the server name before you can edit the credentials.

    Regarding the error, is TNSOraName file setup correctly? Can you TNSPing the Oracle server / connect to using Oracle tool like SqlPlus?

    The OraOLEDB.Oracle.1 provider is not registered

    SSDT is a 32 bit application and requires 32 bit ODAC; you have to install that as well.

    Hi Zoe and OlafHelper,

    Thanks for providing the details.

    I installed wrong 32 bit version . Now i have installed proper 32 bit version ODAC and updated the tnsnames.ora in both the locations (32 bit and 64 bit).

    Thanks for your great help.
