Hi jmays3081 and welcome to our community
I'm not sure where you are trying to do this. Are you trying
to download Captivate from the web and the installer isn't opening?
Or have you installed some other software that offers Captivate as
a trial and it's not opening from there? Or have you downloaded
already, but Captivate refuses to start after you have downloaded
and installed it?
Here are some links that might help.

Hopefully one of these links will help resolve your issue. If
not, post back and we will try to help you out.
Sincerely... Rick
