Lately, more and more users are complaining that I can no longer install various applications on Mac. Adobe Photoshop, Dreamweaver, Illustration, Lightroom and others in the suite Adobe 2020, I'm no exception.
When trying to install an application, the message appears:
The installation cannot continue as the installer file may be damaged. Download the installer file again.
It is worth mentioning that we are talking about installing a applications downloaded from the Internet, whose DMG installation archive is stored locally. The error does not appear for applications in the App Store.
How to fix the error “The installation cannot continue as the installer file may be damaged. Download the installer file again. "
1. Mount the DMG installation file then inside it, select the file “install"Right-click, then"Show Package Content”To navigate inside it without starting the installation process.
2. Go to the folder “Contents”→“MacOS"And run the file"install".
After this step the application will open Port and it will start running the application installation process.
The tutorial above is tested on Adobe Photoshop 2020, but there are many other applications for which this method works.
