If you're getting an installer being executed, that kinda implies that you're not launching the actual RH exe.
Thanks for the insight, I appreciate it. I have updated both exe files to use x5 without activation but had to no luck after uninstalling and reinstalling. I did look through the rest of the snippets and noticed someone had issues after upgrading Adobe Reader. The user that I was installing the software for upgraded to Acrobat 9, do you think it's possible that could have affected the install?
Sorry I missed your reply.
Acrobat 9 was much later so I guess it could well be related. Can you uninstall all using RevoUninstaller and then try just RoboHelp first? Failing that, version 5 is now old and the output may not be good with all browsers if you are creating webhelp.
