I downloaded Nod32 trial to try it but it wont install on my XP. Extract and installation is working but at the end of the installation I get this error 121 Nod32Mod Winnt English Tried several times,cleaned up registry after each time downloaded new installer but same error in the end. Installation in save mode gives the same error. I have no other antivirus on my computer that could mess upp the installation. Any ideas to fix the error?
