Access 2003 to 2010 Errors

I was able to convert an Access 2003 database (.mdb) to the 2010 .accdb.
Amazing!

When I select a report and then open it I get two errors.

1. Could not find an installable ISAM .

2. “A custom macro in this report has failed to run, and is preventing the report form to render.”

This code is then highlighted in yellow:

Private Sub ReportFooter_Format(Cancel As Integer, FormatCount As integer)

DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel2003, "qryCBAllProg", "C:\flw\Access\", True

End Sub

The 2003 database is on the same computer running Windows 7.

All of the folders and paths are identical.

I'm lost . . . .

Any suggestions?

Thanks . . . Rick
