  2. Select "Quit Creative Cloud"

Note: Don't worry if some processes aren't visible – they may already be terminated. Proceed to the next step after ending all visible Adobe processes.

3. Rename Adobe Program Folders

Incomplete Adobe installations can conflict with new installations. Instead of deleting, safely backup existing folders by adding .old to their names.

Windows Path

C:\Program Files\Adobe\

macOS Path

/Applications/Adobe [Program Name]/

Folder Renaming Examples

Adobe Premiere Pro → Adobe Premiere Pro.old
Adobe Photoshop → Adobe Photoshop.old
Adobe After Effects → Adobe After Effects.old

Pro Tip: Keep the .old folders for about a week after successful installation, then you can safely delete them if everything works properly.

4. Reset Installation Location to Default

  1. Launch the Creative Cloud desktop app
  2. Click the Settings gear icon"Preferences"
  3. Select "Apps" from the left menu
  4. In the "Install Location" section, choose "Default location"
  5. Click "Done" or "Save"
