I had 3.5 free, uninstalled it and then installed 4.0, to give the full features a try. The Shield is not available. On the status screen, Resident Shield shows as n/a. On the Shields tab, it says not available in the free version. Version 18.104.22.168, download file was 22.214.171.124a I thought it was full featured for thirty days. ?? I have a logfile.txt, but no error report. Timer deletion failed, Value: 000003E5 Timer deletion failed, Value: 000003E5 application start was blocked because of several instances I installed as admin user. I had shut down all apps, including AV/Firewall (disconnected from internet) I was able to install properly on a separate system which had never had Ewido on it. Is there some time-out remnant from the old install (3.5) preventing the full features on this system? Thanks.
