Somebody responded to my trouble ticket (this morning) and my problem is now resolved. I was provided with installers for PowerDVD 9 Ultra and then the upgrade installer that allowed me to go from PowerDVD 9 to 11 Ultra. I do not know what the issue was, before, but when I tried to run the PowerDVD Ultra 10 Mark II to PowerDVD 11 Ultra, the installer deleted the old install and then just hung.
Thank you - Mike
