I already owned version 1 of all three softwares. Today I bought the universal upgrade. Once I downloaded from the serif site the three dng files for the installation, they did not install in the applications folder, where I could still find only version 1. I tried to cancel the old files of version one from the folders, but still the opening of the dng files does not result in the creation of any file in the folder of the applications. When I start the dng files they open and at the end of the process open the program, but it functions only temporarily and they disappear when restarting the Mac. Can you please suggest a solution?
