I am running VB.Net 2015, and I want to edit a 2016 database - 64 bit.
I am using the following code:

Dim concstr As String
      concstr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\folder\accessDB.accdb;"
            Dim newcnct As New OleDbConnection(concstr)
                     newcnct.Open()

When it comes to this last line with the Open command, it generates an error.

Yes, and we are supposed to guess what the error is?

Is your VB.net application 64 bit ?

It skips all the rest of the codes and then jumps out to the previous procedure that called this function.

You're probably lacking the 64-bit driver for JET.  you can download it here:

 Visual Studio 2015 is still a 32-bit application

I downloaded it. This is the header of the file
Microsoft Access Database Engine 2010 Redistributable


It did not help the problem.

If you keep the error message secret, we are still left guessing what the error is.

 We'll need some more information then.    Is this a new install, new app, is your code running 32 or 64 bit, and of course as gustav said, what the error is.

It could be anything....

Try this:

1. Open the "My Project" page in Visual Studio.
2. Select the Compile option on the leftside listing.
3. Set "Target CPU" to "x86"
