In Mac OS, Adobe Photoshop Elements or Premiere Elements installations can fail with Exit Code 15. Alternatively, the installer user interface doesn't appear when you click Install.
Note: Safe Boot appears only on the startup screen; it does not appear in the corners of the desktop the way it does in Windows.
- Restart the Mac. Press and hold the Shift key immediately after you hear the startup tone.
- Release the Shift key when the Apple logo appears. Safe Boot appears on the Mac OS X startup screen.
Contact Adobe Support for additional assistance with this issue if the steps above did not work.
