If anyone had the same problem as me: This worked: https://www.youtube.com/watch?v=6fqzb4qpgcs&app=desktop

Edited by Dev (added  instructions from video):
“App is Damaged Can’t Be Opened” or "App is damaged and can't be opened. You should move it the the Trash." error messages in Mac OS Sierra and High Sierra are a common error when you try to install a non-App Store application.

1. Open a Terminal with appropriate privileges (“sudo bash” to make you root on most systems)
2. Enter the following, substituting “AppName” with the real name of the app: xattr -cr /Applications/AppName.app
3. Press Enter to run the command.

Still getting nothing but errors:

Smartmedias-MacBook-Air:~ support$ spctl --add ~/Downloads/RoskmithTools.dmg

/Users/support/Downloads/RoskmithTools.dmg: invalid API object reference

Smartmedias-MacBook-Air:~ support$ xattr -d com.apple.quarantine Rocksmith\ Tools\ Launcher.app/

xattr: No such file: Rocksmith Tools Launcher.app/

I have googled this myself to no help

Terminal:

Smartmedias-MacBook-Air:~ support$ sudo spctl --master-disable

Password:

support is not in the sudoers file.  This incident will be reported.

Smartmedias-MacBook-Air:~ support$

One of the suggestions in the google search results: https://stackoverflow.com/questions/47806576/username-is-not-in-the-sudoers-file-this-incident-will-be-reported

I type: sudo nano /etc/sudoers

Result:

-----------

Smartmedias-MacBook-Air:~ support$ sudo nano /etc/sudoers

Password:

support is not in the sudoers file.  This incident will be reported.

Smartmedias-MacBook-Air:~ support$ sudo spctl --master-disable

I have spent hours trying to fix this with no results

When I try to enter the command in the terminal I get: "User is not in the sudoers file"
