I have a license for Production Premium CS5 and have the boxed software. However, I just recently purchased a new computer that does not have a CD/DVD drive on it. In the past I was able to download the "trial" version of Production Premium CS5 and just activate it with my real key. This was better even when I had a CD/DVD drive as the installation went much faster. I have lost the trial installation file. Is there any way for me to get the older version trial installer now? I'd like to get everything installed but it looks like my only solution at this point is to go buy an external USB CD drive just to use this one time.
