If macOS says "STEP 1 - INSTALL.command is damaged and can't be opened":

Do this exactly:

1. Make sure the ZIP is extracted first.
   You should see a normal folder, not the ZIP preview.

2. Move the extracted folder to your Desktop.

3. Rename the folder to:

ZOOMWTF

4. Open Terminal.
   You can press Command + Space, type Terminal, then press Return.

5. At the Terminal prompt, paste this and press Return:

cd ~/Desktop/ZOOMWTF

6. If the next line starts with ZOOMWTF or shows no error, paste this and press Return:

xattr -dr com.apple.quarantine .

7. If it says Permission denied, paste this instead and press Return:

sudo xattr -dr com.apple.quarantine .

Your Mac may ask for your password. Type your Mac login password and press Return.
The password will not show while you type. That is normal.

8. At the next Terminal prompt, paste this and press Return:

chmod +x "STEP 1 - INSTALL.command" "STEP 2 - OPEN ZOOM.WTF.command" "ZOOM.WTF.app/Contents/MacOS/ZOOM.WTF"

9. Close Terminal.

10. Double-click STEP 1 - INSTALL.command.

11. Double-click STEP 2 - OPEN ZOOM.WTF.command.

Why this happens:
macOS can quarantine unsigned apps and command files downloaded from the web.
The app is not missing files; macOS is blocking the first command before it can
run the installer cleanup.
