How to call MS Access MACRO from C# without creating access object

Question

I'm working on an environment that I don't have Microsoft Office installed, but the access runtime is installed.

The scenario is that I have an access file containing linked tables to excel and my problem is the way to update the connection string of these linked tables.

I have created a module function and a macro in order to do the update.

The problem is to call the macro or the module function function in a way without creating an access object because doing so will raise an COM exception.

If there a problem to my solution? If not what are the alternatives?

I have found a solution that I have adopted in my solution.

public void UpdateLinkedTablesConnectionString()
        {
            try
            {
                //Get the excel file location from the directory of the current assembly since the .accdb and the .xlsx are in the same directory location.
                string currentAssemblyDirectoryName = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
                StringBuilder strPath = new StringBuilder();
                strPath.Append(currentAssemblyDirectoryName);
                strPath.Append(Common.GetResourceValue(_directory_DataInput, false, null));
                strPath.Append(Common.GetResourceValue(_excelFileName, false, string.Empty));

                ADODB.Connection Con = new ADODB.Connection();
                Con.ConnectionString = myAccessDatabase.ConnectionString;
                ADOX.Catalog Cat = new ADOX.Catalog();

                Con.Open();
                Cat.ActiveConnection = Con;
                List<string> lstLinkedTablesNames = GetTablesNames();
                foreach (string name in lstLinkedTablesNames )
                {
                    Cat.Tables[name].Properties["Jet OLEDB:Link Datasource"].Value = strPath.ToString(); 
                }
                
                Con.Close();  
            }
            catch (Exception exception)
            {
                throw exception;
            }
        }
