I got a new MacBook Pro running Mac OS Sierra and tried to install Adobe Creative Suite CS5.5 on it, which I already had running on my old MacBook Pro. I downloaded the package directly from the Adobe web page, but when running the Install.app from the disk image I get the error message:
“Install.app” can’t be opened. You should eject the disk image.
Visit the Adobe Creative Cloud website. Once you have signed in using your Adobe ID, you will see all of apps from which to choose from. Clicking an app will give you a description and feature overview to help you decide which to install. Install the Adobe AIR Runtime. Steps to follow on Windows: 1. Go to C: Program Files (x86) Common Files Adobe AIR Versions 1.0. While holding the “Ctrl” key, select the Adobe AIR Application Installer.exe -> Right click on it -> Run as Administrator. Do not take your finger off the “ctrl” key until you see the window open up.
When hitting the help button from that error message I got this explanation:
I searched the web and ran into suggestions to disable the Gate Keeper functionality from the Terminal, to be allowed to install software from unidentified developers, but this did not work for me.

I had to search for it for quite a while, but finally I found a solution to this problem, which I would like to share here as well.
I found it in this thread: https://forums.adobe.com/thread/1098181 from user 'ralfellis'.
Before running the installation, all attributes of the disk image need to be removed. https://ameblo.jp/tildatinsamp1988/entry-12639576095.html. Get the correct path (***) to the installation disk image and run this line in the Terminal: Popsql free download for mac.
This did the trick for me and thereafter I could run Install.app without getting any further error messages from the system.
