I uninstalled Symantic 10 Antivirus, and when i wanted to install Symantec 9, i kept on receiving the following message, “InstallShield Wizard Completed- The wizard was interrupted before Nortan AtinVirus Corporate Edition could be completely installed. Your system has not been modified. To complete intsallation at another time, please run setup again. Click Finish to exit the wizard.”
Please i need help, since several machines are now operating without antivirus.
