Windows 10 - The operating system is not currently configured to run this application

Hi George Jiang,

While reporting this issue in the Microsoft Admin Center Support i came across this message: Using DAO (Data Access Objects) API fails from external applications

This is a known issue and is plannend to be resolved around October 11, 2022.

There is also a workaround for this issue described in the link above. Create an ADODB (or OleDb) connection first and after that you can create an DAO connection:

Dim objConnection

Set objConnection = CreateObject("ADODB.Connection")

objConnection.open "Provider=Microsoft.Ace.OLEDB.16.0;Data Source=c:\temp\Database1.accdb" ' ensure Data Source points to a database that exists

objConnection.close

Dim DBEngine

Set DBEngine = CreateObject("DAO.DBEngine.120")

I can successfully use this workaround in my 64 bit c# net 6 project by creating a OleDb connection first and an DAO connection afterward:

using OleDbConnection oleDbConnection = new("Provider=Microsoft.Ace.OLEDB.16.0;Data Source=c:\\temp\\Database1.accdb");

await oleDbConnection.OpenAsync();

await oleDbConnection.CloseAsync();

DBEngine dbEngine = new DBEngine();

Database database = dbEngine.OpenDatabase("c:\\temp\\Database1.accdb");

While this is annoying there is a workaround and there is a resolution date.
