I got this from a blog and I will paste this for you after this main body: macOS Gatekeeper may prevent older Adobe installers or software from starting: Gatekeeper is an Apple security feature (added in Mountain Lion) that helps prevent malicious applications from running. If you run Adobe installers or software released before Gatekeeper, you should know what to do if Gatekeeper prevents Adobe software from starting. Adobe covers that in this tech note: Error “has not been signed by a recognized distributor” | Launch Adobe applications | Mac OS. The short answer is to bypass the error by right-clicking the application icon, then choose Open from the context menu. Depending on the Mac you use, instead of right-clicking you can also Control-click, or if you have a trackpad set up for two-finger secondary click you can do it that way instead.
“Installer Failed to Initialize” error, or installer failing to run. Some Adobe installers may fail to launch silently, or with the error “We’ve encountered the following issue. Installer failed to initialize. This could be due to a missing file. Please download Adobe Support Advisor to detect the problem.”
Installer Failed to Initialize” error.
Unfortunately, Adobe Support Advisor no longer exists, but there is an immediate workaround that should get the installer going:
Right-click (or Control-click) the installer and choose Show Package Contents.
In the Install window that opens in the Finder, go to the Contents/MacOS folder, and in there, double-click Install. That will open the Terminal application, some lines of code will automatically run, and the actual Installer should successfully launch.
Make a note of this workaround, because any pre-CC installers are unlikely to be updated.
The error message is documented in an Adobe help page: Installing Creative Suite on macOS 10.12 (Sierra). But I found that the same workaround helped when the Photoshop CS3 installer silently failed after I double-clicked it.
