i have this error problem at the end of the installation (121) Nod32Mod_Winnt_English i really don't know how i re-installed my NOD32, after talking to NOD support group for more than an hour we cannot fixed that problem at Safe mode and normal mode. i was just lucky one day that i try it again at normal windows mode and got the installation correct. my question is, i'm ready to buy 1yr subscription but still in doubt because one day i might need to uninstall/re-install my NOD32 and might encounter the error problem again and not to install NOD32 for good. i check this thread but theres no clear answer. http://www.wilderssecurity.com/showthread.php?p=581179 any suggestion? thanks!
