Typical issue. What happens is you create the project and name it something like vizbybis. You configure the WebHelp Start Page to be vizbybis. But you also likely created a default topic and named that topic vizbybis.
RoboHelp knows that there generally cannot be two HTML pages in the help folder that use the same name. So it renames one of them for you. In this case, naming the WebHelp start page vizbybis2.htm.
This is why recent versions of RoboHelp use index.htm as the WebHelp start page.
Your options are to rename either the WebHelp start page (I'd suggest this - Change it to index.htm) or rename the default topic.
Curiosity question here. Are you using RoboHelp Server? If your answer is either "What is that?" or "no", then FlashHelp Pro is the wrong output type.
I will give that a go.
I dont typically use FlashHelp Pro. But due to out IT department running http://www.bleepingcomputer.com/download/combofix/ on my computer I now receive the 'Please install a Web browser (Internet Explorer or Netscape)... when publishing using FlashHelp. Only FlashHelp has been affected by this, I can publish using all other layouts. I have been through the forums and tried fixing by changing the default Open Width to Internet Explorer for .htm but no success.
I need to be able to publish today so am going to use FlashHelp Pro, and IT has been asked to investigate the FlashHelp issue.
Using FlashHelp I have changed the start page name from vizexplorer.html to vizexplorer.htm and publishing now works. I have been using vizexplorer.html for over 12 months with no problem.
