This was RoboHelp 10 free trial. I have a 64 bit windows machine, and wonder if this has any effect?
Akamai download manager is just a download manager used to download Robohelp.
Have you downloaded Robohelp and installed?
If yes, then please check 'Start' > 'All Programs' and see if robohelp is listed there. You can also check 'Control Panel' > Programs and Features' and see if Robohelp is listed there.
If not you need to install the software.
