I found my registration code in the system registry of my older laptop. My version on that laptop is 5.04. I had recently purchased a new laptop and had everything transferred from my old laptop. When I did that, the machine took my copy of Encore back to demo. To find your registration, go to “regedit. Once in the application, type “Encore” in the search box then hit enter. There are multiple areas within the system registry for Encore. I found my registration code after about 6 clicks of the enter key as each click takes you to a different section of the system registry. The only way I was able to recognize my code was that I remembered it being a series of letters and numbers in groups of four and it started with “K”. Copied/pasted that code into the registration window of Encore. It worked!!!! Hope this helps.
