Failed exporting workbook to fixed format.

Hi,

We're currently developing a web app using PDFTron SDK, we're currently having issues regarding the conversion of .xls files, we are getting this error. We already set the Application Pool to run as LocalSystem identity. Any assistance would be of help.

Exception:
Message: An error occurred while converting the file.

Does this happen with any excel file, or only certain ones?

Can you convert when running as a "normal" process? The error only occurs under IIS?

What about Word or Powerpoint conversions?

[Viczenn Reyes]

I've tried using your Sample projects (ConvertTest.cs) to convert the excel file which I am using to test this, which succeeds in converting the file but when I implement it in our web application it fails.

I was able to convert .doc using .WordToPDF() method and .ppt using .ToPdf() method using a printer.

I suspect the print spooler service is not activated. See this post for more info.

If that doesn't help, is the Excel application registered/licensed?
