Error 121 Nod32Mod Winnt English . I could not install the new updated NOD32. Got this message. Read a load of complete bollocks all over the net. What I did was think what I had done lately - installed Windows INstaller v3 so as to be able to install a new game demo. So I restored my image of C: back to before I had done this and end of problem. Well, actually it was a fix. The problem is that Eset has decided to use the bloody awful .msi method now. Its crap.
