Open Access 365 Database

[Kevin Marois]

I'm trying to open an Access 365 database in C#

private void LoadDatabase(string fileName)
{
var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.16.0;Data Source={0}", fileName);

DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.OleDb");

DataTable userTables = null;

using (DbConnection connection = factory.CreateConnection())
{
    // c:\\test\\test.mdb
    connection.ConnectionString = connectionString;
        
    // We only want user tables, not system tables
    string\[\] restrictions = new string\[4\];
    restrictions\[3\] = "Table";

    connection.Open();

    // Get list of user tables
    userTables = connection.GetSchema("Tables", restrictions);
}

}

On the Open line I get

"The 'Microsoft.ACE.OLEDB.16.0' provider is not registered on the local machine"

I've been Googling this and just about every result says to get the Access 2007 or 2010 driver(s) from [here](https://www.microsoft.com/en-us/download/details.aspx?id=13255), which I did. I still get the error. Anyone know what's wrong?

If it's not broken, fix it until it is. Everything makes sense in someone's mind. Ya can't fix stupid.
