dll not working

I have an old dll that I've been using over the years -- on my main computer the options with a member pop up -- but they do on an older system.
I have the same dll and same version of vb6 on both computers.

on main computer (windows 7)
Sub RecordsetReport()
Member of PrintPreview5.Preview
Create a report from a recordset.


on older computer (windows 7 and windows xp)
Sub RecordsetReport(oRecordset As Recordset, [Headers As Boolean = False], [bWidths As Boolean = False], [etsStep As eAutoStep = 1])
Member of PrintPreview5.Preview
Create a report from a recordset.

I've searched through registry and everyplace I can think.
Any help would be appreciated
