Issue: 
You may get an error message similar to below when you install software
“Photoshop Update” is damaged and can’t be opened. You should eject the disk image.“Photoshop Update” is on the disk image “Photoshop_Update.dmg”. Safari downloaded this disk image today at 6:51 PM from www.adobe.com.

Reason:
This is due to the GateKeeper security feature added in OS X 10.8 (Mountain Lion). In MacOS Sierra, it is a compulsory that all applications have to be identified developer or downloaded directly from AppStore. 

Workaround:
We need to remove the attributes added by MacOS when the application is downloaded from the internet.

​Open Application>Utilities>Terminal.app, and type the following.
xattr -c /Users/******/Downloads/*******.dmg   (make sure that is the correct path to the correct installation file you are having problems with.)

If you get no error, you may run the software again.
