I don't think it is IE7. I just created a test and put on a button as you describe. It failed under IE7 but then I found it also failed under IE6. Tracked it down to having used a PDF with a space in the filename. When I pointed the button to that file, there was a space. By the time RH had put it into the output, the filename had an underscore in. When I changed the source to have an underscore, changed that in the skin editor and regenerated, it all worked fine.
Peter, thanks for your reply. I have checked my project and the pdf has underscores but no spaces in the name. Any other suggestions appreciated.
Can you recreate this in a new one topic project?
If yes, zip it up and send it to me. Go to my site to contact me.
I'm having the same issue, but only with Internet Explorer 11. The PDF files open fine with Chrome and Firefox.
I'm using RoboHelp 2015 and the latest Distiller and Acrobat software. In RoboHelp, I create Baggage Files and link the PDF files to those. I then create a new TOC page for each PDF as a link to these files.
Does anyone know of any resolution for this IE problem?
