Why Does Excel 2013 Crash When VBA Creates Connection To Access 2016 Database?

[MatthewNYC]

Hi,


I am running the following software:


Windows 7 (64 bit)
Excel 2013 (32 bit)
Access 2016 (32 bit)


When I use the following VBA code to connect Excel 2013 to my Access 2016 database, Excel immediately crashes:


---- begin ----
Dim objConn As ADODB.Connection
Dim strDBConnection As String


strDBConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Me\Documents\MyAccessDB.accdb;Persist Security Info=False;"


Set objConn = CreateObject("ADODB.Connection")
objConn.Open strDBConnection
---- end ----


I then tried using LATE binding and unchecking the reference to "Microsoft ActiveX Data Objects 6.1 Library" in Excel 2013 and ran this code:


---- begin ----
Dim objConn As Object
Dim strDBConnection As String


strDBConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Me\Documents\MyAccessDB.accdb;Persist Security Info=False;"


Set objConn = CreateObject("ADODB.Connection")
objConn.Open strDBConnection
---- end ----


In this case Excel does not crash but reports the following error:


Method 'Open' of object '_Connection' failed


I read some message board posts that recommended installing:


Microsoft Access Database Engine 2016 Redistributable
https://www.microsoft.com/en-us/download/details.aspx?id=54920


However, this did not solve the problem.


I even tried using just about every connection string for Access from ConnectionStrings.com but none of them work.


From what I've read in the message boards (but didn't understand completely) the problem may have something to do with the fact that my Windows 7 is 64 bit and the Excel and Acess I am using are 32 bit.


My BIG concern is that I am developing a commercial Excel spreadsheet and now I'm wondering what problems my users will experience with the software depending on their version of Windows, Microsoft Office, and whether both (or one) are 32 or 64 bit.


Is there any Access Guru out there that has this all figured out?

From what I've read in the message boards (but didn't understand completely) the problem may have something to do with the fact that my Windows 7 is 64 bit and the Excel and Acess I am using are 32 bit.

not a problem

I have
MS Excel 2013 (15.0.4641.1000) 32 bit
MS Access 2013 (15.0.4641.1000) 32 bit
MS Windows 7 64 bit

and have no problems doing what you're trying (of course both my Excel and Access are 2013)

I have the References checked
Visual Basic for Applications
Microsoft Excel 15.0 Object Library
OLE Automation
Microsoft Office 15.0 Object Library

I suggest checking your anti-virus software

Hi James,

Thank you for trying to help.

In Excel / VBE Editor / References, I unchecked the box for:

Microsoft Office 15.0 Object Library

Then, when I went to recheck it, I now saw it had changed to 16.0:

Microsoft Office 15.0 Object Library

I'm assuming this is because I installed Access 2016.

The VBA code now makes the connection without raising any errors.

However, when I attempt to create a simple recordset object I get this error:

Method 'Open' of object '_Connection' failed.

Here is the code:

SQL = "SELECT * FROM settings"


Set rs = objConn.Execute(SQL)

I don't understand why Microsoft makes something that should be so simple, so difficult.

THis doesn't look like it would work:

SQL = "SELECT * FROM settings"
Set rs = objConn.Execute(SQL)

Did you post all of your code?
