Hello Anne! Thank you for your question. I will be assisting you today.I'm sorry about the issue. Can you please confirm the model of your Canon camera? I cannot see any model with C-150. Please check the label(s) on the camera for any other model.

Can I provide you the camera software online, so you can download and install on your computer?When you are available, please reply back at the box below to continue. Thank you,
