Error 48 Unable to load dll

[RGregoire]

Help

I had created a program about a year ago that among other things it would create a report and give you the option of previewing it, printing it, or exporting it to Excel.

Back when I made the program the export to Excel worked fine. Now, when I try the export to Excel function I get an error -

Error 48 Unable to load dll.

I have narrowed this error to the statement in code -

Set XApp = CreateObject("Excel.Application.9")

I am using Excel 2000 which is Excel9.

I have researched this error here and at the MSDN site. From what I have learned, I'm guessing is that a dependent dll file has changed or is missing. If that is the case, how do you determine which dll file is causing the problem.

Thanks in advance
