excel - Can't change Link Datasource through ADO for accdb format

Question

I am trying to add a linked table to an Acccess database using ADO and ADOX (from excel).

However everytime I try, I receive the error: "Microsoft Access does not support linking to an Access database or Microsoft Office Excel workbook saved in a format that is a later version than the current database format."

Both the linked table and the target database are made using Access 2010 and are of the .accdb format. My code:

    Set cat = New ADOX.Catalog
    Set tbl = New ADOX.Table

    ' Open the catalog.
    cat.ActiveConnection = objConnection

    tbl.ParentCatalog = cat
    tbl.Name = "Promotions"
    tbl.Properties("Jet OLEDB:Link Datasource") = strCurrentPath & _
        "LocPrcCh.accdb"
    tbl.Properties("Jet OLEDB:Remote Table Name") = "Promotions"
    tbl.Properties("Jet OLEDB:Create Link") = True
    tbl.Properties("Jet OLEDB:Link Provider String") = _
        "MS Access;PWD=XXXXXXXXX;"

    cat.Tables.Append tbl

Returns the error after the last line. Any ideas how to make this work?

Solved it.

My target file had the .accdb extension, but it was not in the 2007 format. When opened it said it was a 2002 - 2003 format access file.

The file was created in Access 2010, but the format was later changed I used a jetengine compacting function elsewhere in my program, which created a new version of the database in an older format.
