I have trouble when installing, I keep getting error1321 installer has insufficient previliages to modify. I have looked through another post for another adobe product, but when I go to change something I keep getting access denied. I have also noticed that some of my programs I use are either missing there shortcut or I cannot access them. It seems to have started after loading kepersky. Not sure if it is the problem but i am getting very frustrated with the issue. Please help...
