I have installed Topaz Adjust plug in filter in both CS6 & Lightroom 5.7 it works well in CS6 but when I go into lightroom and go to photo,edit,fusion express I get a message stating that QtGui 4.dll is missing try reinstalling the program which I have done.I have been in touch with Topaz and tried all they have suggested and also with Reg cure without success . Has anyone had this same problem.Thank YouKeith Green
