Can you continue to use ZoneAlarm if you don't renew your License / Subscription? Updated 30 settembre 2017 11:39 If you prefer not to renew your license, you may continue to use the last version that was available while your license key was still valid. If you uninstall and try to re-install an expired paid version you will not be able to install it again. In this case please download and use a Free version of ZoneAlarm. This does not apply to ZoneAlarm Anti-Ransomware and ZoneAlarm Mobile Security. NOTE: Some features and functionality may be disabled if you choose not to renew your license along with no official support from ZoneAlarm for your software.
