It was recently brought to my attention that users working through my Adobe Robohelp HTML 9: The Essentials book ran into trouble on page 278 (during the ePub activity).
When I wrote the RoboHelp 9 book, 7za was the utility that Adobe used to assist in the creation of ePub files. On page 278 of my book, users are instructed to browse for the 7za file (which I included within the book's data files folder). The problem is that Adobe released a service patch (9.02) about 9 months after the book was released and ended up replacing 7za with another utility called zip.exe.
Anyone using the patched version of RoboHelp hit a brick wall when trying to load 7za since RoboHelp 9.02 requires zip.exe.
Here is the workaround: Click the Open in browser button (as shown in the screen shot on page 278 of my RoboHelp 9 book) and save the zip.exe utility to your computer. On page 278 of the book, use zip.exe instead of 7za. If you are having trouble grabbing the zip.exe utility via your web browser, here is a direct link to zip.exe.
The good news is that the ePub feature is totally integrated in the new RoboHelp 10, and there isn’t a zip utility required at all.
