Hello, I am having lots of difficulty and in need of help. I have a laptop that started as a Vista home premium system with the trial version of NOD32 installed about a month ago on it. Yesterday I ran the Win 7 Home Premium upgrade on it. However, I did not read the Eset instructions before starting so I had not done an uninstall of NOD32 before the upgrade. Now I did try running uninstall after the upgrade but it clearly did not clean up everything. I still had the Ekrn service running so I disabled it and deleted the file directories from Safe mode. I still get authorization errors when I try to run an install now on some objects about halfway thru. So I am stuck partway installed. What can I do now to get over the hump?
