Sony PCG-TR1A - Manual (Page 194)

Why does the message, "You must insert the Application CD into your optical drive" appear, and the
program does not start?
 Some programs may require specific files located on the Application Recovery CD. Insert the disc, and try starting
the program again.
 Your optical drive may not be reading the disc.
 Make sure you place the CD in the tray with the label facing up.
 (For computers with external optical drives) Make sure the optical drive is properly connected to your
computer.
