Well, to figure out where the error is coming from, and what line is causing the error, you should have proper error handling for your debug/beta testing. As an example...
Code:
Private Sub Form_Load()
 
On Error GoTo Form_LoadError
 
Exit Sub
Form_LoadError:
 
MsgBox "FormName.Form_Load " & Err.Number & ":" & Err.Description
 
End Sub
You can also add line numbers and use Erl (see MZTools for a nice addin for VB6.0 dev environment) to track down exactly which line is causing the problem. Also, put Option Explicit at the top of each code window, as this will force you to declare everything. Then if you have any On Error Resume or On Error Resume Next or On Error GoTo 0, remove them for proper error handling and in the future so you do not have to add this manually, goto tools>options and put a checkmark next to Require Variable Declarations. Then any new projects will automatically have Option Explicit at the top of each code window...



Good Luck

I already mentioned that the error was

"class does not support automation or does not support expected interface"
"Error No-430"

But where? What line of code? What code executed before the error? All these things, and more, add up to why errors happen...

Hi, you can also try this VB.NET Excel component which has no dependency with MS Office.

Here is a Hello World example to create excel file in VB.NET:
Code:
Dim workbook = New ExcelFile()

' Add new worksheet to Excel file.
Dim worksheet = workbook.Worksheets.Add("New worksheet")

' Set the value of the cell "A1".
worksheet.Cells("A1").Value = "Hello world!"

' Save Excel file.
workbook.Save("Workbook.xls")
