Am running ZA Pro V9.3.014.000 along with Free version of AVAST anti virus. Downloaded and tried to install ZA V100.250.000 When I try to install, I get the following message. "Zene Alarm can not be installed on a system already has AVAST Antivirus installed. Your system does not meet the installation requirements." What is this conflict between a FireWall and a AntiVirus program. I have been a ZA customer more years than I can remember.
