Hi, I can not complete the install, I get a missing file error please re install, I have many times. Tech has been as helpful as they can, I think, they have sent me 2 different downloads, same problem each time..."missing file please re install". I completely remove previous installs and I even tried re installing on top, PD will not do that until previous install is removed. I have Vista. So if anyone has the key to this problem you will make a happy man happy, I did like the trial version so much, Thanks, Darryl
