Error while reading excel file on windows 7 machine

Hi,

We have a WebSpeed Application (OpenEdge 10.2B & ps:eScript 1.90), that uploads order lines via an Excel file.

It works fine on Windows XP and Windows Server 2003 machines, but gives an error in the server log on Windows 7 machines (see below)

The error occurs at the following code point.

hexcel:Workbooks:Open(cdestPath).

Windows 7 Error:
