We’ve deployed our solution to a new server (WS 2008 R2/IIS 7.5) with the latest version of Aspose.Words (11.7.0.0). The checkboxes come out as circles on the new server (see attachment), but come out fine on the development machine. The document is saved in pdf format:
Aspose.Words.Saving.PdfSaveOptions saveOptions = new Aspose.Words.Saving.PdfSaveOptions();
saveOptions.SaveFormat = SaveFormat.Pdf;
// saveOptions.UseHighQualityRendering = true;
doc.Save(Response, "Contrat.pdf", ContentDisposition.Inline, saveOptions);
