XLapp.Workbooks.Open is not opening XL app but path is correct
 

I'm trying to write access data to Excel spreadsheets, and even though the
path I give is correct and the XL workbook is present and correctly named,
the application is unable to find it. I'm at a loss on this one. Is there a
control I'm missing or could it perhaps be the low security my IT dept has
given me makes it difficult to operate XL remotely?
