Robohelp 2019 classic : links to pdf documents do not work anymore in CHM

Hello,

In the past a could perfectly insert a hyperlink in a topic to a pdf document I placed in the shared resource directory. link to file, Display in new window. The file appears in the bagage files. And clicking on the link opened up the file in kind of browser.

 

Not sure since when but my actual configuration (win11, projectfiles in a one drive directory) doesn't work.

Nothing is happening when clicking on the link

when opened from within robohelp 'view result' or primary output view, nothing happens. When using the file explorer I get this message

I tried a file name without spaces but got the same result

Tried the same chm on a different machine (an RDP server with IE explorer still being present) and there the pdf file is shown in the IE browser which is still installed.

So I suspect there is something wrong in between the creation of the chm the link and the presence of IE as browser.

Does any one have a solution?

 

best regards

Olivier

    Pretty sure this is a Windows issue & not a RH one. CHMs are so ancient these days that getting them to work in more secure environments is proving to be difficult.

    Hello Jeff. You were right about the issue being in HH.exe (the runtime for chm's). This executable calls dll from IE to present pdf files. Theses dll do not exist anymore in WIN 11. And so 'nothing' happens. So it seams Microsoft has not maintained HH.exe. Which is a bad sign. Very bad
