PowerPoint Embedded Links Issue

We’re experiencing issues when rendering PowerPoint files that contain links with multiple query string keys/values (thus the resulting URL contains an “&” within the address). It seems that the GroupDocs generated SVG document shouldn’t contain an “&” in the URL, but instead, replace these with the corresponding HTML entity (&) - see

We are using version 17.8.0 of GroupDocs.Viewer

Thanks in advance,

Thanks for using GroupDocs.Viewer for .NET. Would you please share with us the problematic PowerPoint document? We look forward to hearing from you.

Sure, no problem. I’m only able to upload images thru here so here’s a screenshot of what we’re seeing in the viewer (the red text is a note I put in) and here is a link to download the .pptx:

Thanks for providing the problematic document. We are able to reproduce your reported issue with version 17.8.0 of GroupDocs.Viewer for .NET. However, the issue is fixed in the later versions (17.9 and greater) of the API (see output). We recommend you to please upgrade the API to the latest version to get rid of this issue.
