Problems with instilling Captivate 9 on my Mac
Good evening all,
I have just purchased, online, in my Adobe account, Captivate 9. It gave me an option of all the files for both Windows and Mac to choose to download. As I am working on OS Mac system I chose the three dmg files and downloaded them. Once downloaded completed, I made sure all Adobe apps were closed as well as my other programs, then tried the insulation. However, I cannot get Captivate 9 to install.
The following is a screenshot with the error message I get when I try to install. Can anyone tell me what I am doing wrong please.

Many thanks
David
