We have a few systems here that we installed NOD32 3.x on early in the summer using the previous licenses information, which expired in September. Recently we renewed the licenses, but when I would enter this information into NOD32 and click Update, it would appear to start the update, but then fail with error 0x101a.
Searching on the ESET support site I found a Knowledge Base article (
http://training.eset.com/kb/index.php?option=com_kb&Itemid=29&page=articles&articleid=537) that mentions to un-install NOD32, restart the system, delete a folder, then re-install the software to correct this issue. That wasn't an option for me, but I found that if you use Task Manager and use the "End Process" on "ekrn.exe" and "egui.exe", then restart NOD32, this fixed the problem.
