ADODB.Connection General Error only for some users?

[RadioWriter]

Hello all-
Working on a tool which imports old Excel workbooks into a formatted workbook, then exports the formatted workbook to Access tables. It's working perfectly on my machine, but when my co-worker tries to run it, he gets "[Microsoft][ODBC Microsoft Access Driver]General error Unable to open registry key Temporary (volatile) Ace DSN for process" on line 6 of the following code-

Sub exportInformation()
    Dim cn As ADODB.Connection, rs As ADODB.Recordset, iXCoord As Integer, sSheet As Worksheet, iRow As Integer, toAdd As Boolean, crs As ADODB.Recordset
    Set sSheet = ThisWorkbook.Sheets(1)
    Set crs = New ADODB.Recordset
    Set cn = New ADODB.Connection
    cn.Open "Driver={Microsoft Access Driver (*.mdb, *.accdb)}; Dbq=Z:\_Database\TestDatabase.accdb; Uid = Admin; Pwd = ;" '<-- Causes error
    Set rs = New ADODB.Recordset
    rs.Open "BOM", cn, adOpenKeyset, adLockOptimistic

Z:\_Database is a folder that he is connected to (and has permissions for), and when he runs it through another path it works fine. We are both running this code from Excel 2013, we've checked our References to make sure they match... Most of the solutions I've seen have said to either try restarting the computer to get rid of any residual exclusive instances of the database or to check the permissions, but neither solution has helped. Any thoughts on the matter would be greatly appreciated.
Thank you in advance!

I'm not at all familiar with ADODB, but the error message mentions a DSN. You might make sure that your co-worker has the same DSNs as you do.

Yup. (Or, well, I guess I'm a little unclear on what a DSN is... After some fairly extensive searching, I'm pretty sure I've got this right.) Same file path, file name... I'm PRETTY sure this should be a DSN-less connection string anyway. It's an ODBC Driver. (I got the Connection String structure from https://www.connectionstrings.com/mi...dard-security/ <-- there)
