Query: Extremely disappointed!!

I just recently purchased this photo keychain. When I received it, it was new in the package. It did not have a software installation CD with it. I thought maybe I could just plug it in to my computer and it would load the software or something like that. When I tried it, it didn't work. I went to the Coby website and downloaded the software and tried to run the setup. I keep getting a message that says it is owned by another program and it will exit. I have tried everything that I know to do and nothing works. I absolutely do not recommend this product to anybody. I have never had so much trouble installing anything in all my life. It's a complete waste of money!!
