Install Captivate Demo Fail

[Kathryn_Burns]

Everytime I try to install the Demo I get this error.

I have Mac OS X 10.6.8 (160 GB of free HD space) I haven't a clue what the problem is.

I just tried to duplicate the install behavior which you are experiencing but I was unable to.  From the screen you posted it looks like you are trying to install the Akamai download manager 2.0 but when I just started the download of Captivate CS5.5 it used Akamai Download Manager 3.0 which does not install anything.

Did you try to download Captivate CS5.5 from http://www.adobe.com/cfusion/tdrc/index.cfm?product=captivate&loc=en%5Fus?

Which web browser are you using btw?  Have you tried a different web browser?

Try to uninstall the Akamai Download Manager and then re-download Captivate form the above link mentioned by Jeff and try installing it. Check if it gets installed.
