I am using CS5 on a 64bit Windows 10 Home computer. I have been authoring DVDs using Encore for several years and been more than happy with it. This week, out of the blue, I have been getting the message "the player used to create the project could not be found, defaulting to adobe player" when I attempt to open exisiting files, and a simlar message when creating a new file. With a new file, Encore simply shuts down when I Ok the message. I have reinstalled the software from CD, tried running as Administrator, to no avail.
Have something to add?
