Power DVD software

YES I’M A NEWBIE!!! My computer crashed a while ago and we had to send it off to a factory to get it repaired. The problem is when we got it back they had deleted everything off it!!. I got everything back except for the powerdvd software, the powerdvd program was already onthe computer when we got it.but it didn’t come with any instillation cd’s or disks at all. (Don’t ask me why!! i’m not an expert)! Anyway, is there anyone who could tell me where i could get a free copy of the software from? If you know then please include the companies or website addresses please.THANK YOU !!! :bow:
