NotImplementedException when viewing certain ZIP file in .NET

When trying to View this specific ZIP file, or call GetViewInfo, the following exception is thrown:

System.NotImplementedException: 'No other compression methods implemented.'

We are using GroupDocs Viewer 21.5.0 without this code:

        using (var viewer = new Viewer(documentPath))
        {                
            var info = viewer.GetViewInfo(ViewInfoOptions.ForHtmlView());

            var options = HtmlViewOptions.ForEmbeddedResources(@"D:\output\output_viewer{0}.html");
            viewer.View(options);
        }

This was found by our internal QA engineers apparently by packing copies of the same TIF file into one big ZIP file. They were just using Windows Explorer for the compression.

Hi @Clemens_Pestuka

The issue is reproduced, but when I try to reproduce the issue by recompressing these files in my windows explorer - the issue is not reproduced. I think we need to compare our version of OS.

What OS QA engineers using?
What build version of OS?

I tested on:
Windows 10 Pro, Version 1909 OS Build 18363.1500.
