Connecting to Access 2016 from .Net application RRS feed

  • Question

  • I am using the connection string "PROVIDER=Microsoft.ACE.OLEDB.12.0; to connect to an Access 2016 database

    but I get "The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine."

    The solution seems to be to install "Microsoft Access Database Engine 2016 Redistributable 64-bit" and I downloaded it via the link

    <cite class="_Rm" style="color:#006621;font-style:normal;font-size:14px;"></cite>https://www.microsoft.com/en-gb/download/details.aspx?id=50040

    However, when I run it I  get

    Error message Click-to-Run : Office 365 - can't work with Installer

    How to I connect to the database?

  • Hi iLens,

    The following link provide a solution about this issue, please refer to:

    The ACE provider is not installed on Windows operating systems by default. You have to install it. The ACE provider is available in two forms: Microsoft Office Access database engine 2007 and  the Microsoft Access Database Engine 2010 Redistributable. The 2007 version is only available as a 32-bit component whereas the 2010 version offers both 32 and 64-bit options. You need to be careful which option you choose, because a wrong choice here is the most frequent cause for the error message.
