Hi there,

When I try to add help content to MS Help Viewer 2.3 I get a error message:  For security reason DTD is prohibited in this XML document...

For full detail see attached screenshot. 

And my question is what can I do on my side to add WPF Help File content to my help viewer?

Hello Bill,

Thank you for sharing this with us!

I will forward it to our developers for further investigation. I was able to reproduce it with Help Viewer version 2.3. Using Help Viewer 2.2, on the other hand, is working fine. As a workaround, until this is resolved I would suggest you either use this version or use the CHM offline documentation. The online documentation would also be an option.

Hello Bill,

Could you please try cleaning any cache that may have maintained from previous installations of the documentation and try again?

The Help3 documentation is normally stored in "C:\ProgramData\Microsoft\HelpLibrary2\Catalogs\VisualStudio15\ContentStore\EN-US". Please also remove the references to this documentation in the "C:\ProgramData\Microsoft\HelpLibrary2\Catalogs\VisualStudio15\ContentStore\installedBooks.{n}.xml" file.

Other remnants could also be stored in the other subfolders of the "C:\ProgramData\Microsoft\HelpLibrary2\Catalogs\VisualStudio15" directory so please make sure that everything is removed before you try the installation again. Do also note that you may need to replace VisualStudio15 with your version of Visual Studio.

Please let me know how this goes.

Hi Dilyan,

The problem was caused by old version of a help file. I cleanup folder C:\ProgramData\Microsoft\HelpLibrary2\Catalogs\VisualStudio15\Incoming\  and successfully imported Telerik_UI_For_WPF_Documentation.

Thank you for your help!
