We have been using Aspose.Excel 3.5 in a web application to download workbooks for several months now. We wanted to track the version of the workbook in the Revision Number of the Excel workbook's properties. However, after we edit this field Aspose.Excel will no longer open the workbook, even if we change the Revision Number field back to blank.
Attached is a screen shot of the Excel workbook properties.
As always, we will download the latest versions of the software.
