"Microsoft.ACE.OLEDB.12.0 provider is not registered" [RESOLVED]
- by Azim
I have a Visual Studio 2008 solution with two projects (a Word-Template project and a VB.Net console application for testing). Both projects reference a database project which opens a connection to an MS-Access 2007 database file and have references to System.Data.OleDb. In the database project I have a function which retrieves a data table as follows
private class AdminDatabase
' stores the connection string which is set in the New() method
dim strAdminConnection as string
public sub New()
...
adminName = dlgopen.FileName
conAdminDB = New OleDbConnection
conAdminDB.ConnectionString = "Data Source='" + adminName + "';" + _
"Provider=Microsoft.ACE.OLEDB.12.0"
' store the connection string in strAdminConnection
strAdminConnection = conAdminDB.ConnectionString.ToString()
My.Settings.SetUserOverride("AdminConnectionString", strAdminConnection)
...
End Sub
' retrieves data from the database
Public Function getDataTable(ByVal sqlStatement As String) As DataTable
Dim ds As New DataSet
Dim dt As New DataTable
Dim da As New OleDbDataAdapter
Dim localCon As New OleDbConnection
localCon.ConnectionString = strAdminConnection
Using localCon
Dim command As OleDbCommand = localCon.CreateCommand()
command.CommandText = sqlStatement
localCon.Open()
da.SelectCommand = command
da.Fill(dt)
getDataTable = dt
End Using
End Function
End Class
When I call this function from my Word 2007 Template project everything works fine; no errors. But when I run it from the console application it throws the following exception
ex = {"The 'Microsoft.ACE.OLEDB.12.0'
provider is not registered on the
local machine."}
Both projects have the same reference and the console application did work when I first wrote it (a while ago) but now it has stopped work. I must be missing something but I don't know what. Any ideas?
