Microsoft.ACE>OLEDB12.0' provider is not registered on the local machine

Question

When I try to connect my programme with the database, a message says

The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

I already installed " Microsoft Access Database Engine 2010 Redistributable "

Have any idea?

Answer 1

Please try the following:

• First, ensure that you have installed the correct version of the database engine; you can download the 32bit/64bit version from here: https://www.microsoft.com/en-us/download/details.aspx?id=13255
• The installed driver can only be used within an application running under the same architecture, therefore, try building your application to run as 32bit or 64bit; you can do this from your project properties, Build tab, please try the following two combinations and see which one works:

Also, you can use the System.Environment.Is64BitProcess property to tell if your process in running as 64-bit.

Hope this helps.
