Dear all, i´m new in this forum and this is my first post. I have a problem trying to install the nod32 smart security beta in mi pc. Previously I had installed a trial version of Nod32 2.7. I uninstall this version from add/remove programs and I restart my pc. Then I ejecute the Nod32 smart beta installer and says that I must Uninstall the previous version of Nod32. So I tried cleaning the windows registry with Regcleaner and Ccleaner. But always says the same error! so I open the regedit and there are a lot of keys for Nod32 and I can´t delete them. Can anyone help me? I attach an error screenshot - Thanks to all!!
