I have tried to install Internet Security on two different computers. When I start the installation, I get a “Non 7Z Archive” error message each time. I downloaded a fresh copy, and got the exact same problem. Any suggestions?
I’m not entirely sure what the issue is, it’s possible that the installer is corrupt, please right-click the downloaded installer and click “Properties” then switch to the “Digital Signatures” tab (If present) and see if it has the Comodo certificate listed there, if either the certificate is missing or the “Digital Signatures” tab itself is missing, then the installer is most likely corrupt as a result of a bad download, I remember someone else had an issue with a corrupt download repeatedly and had to download it from a third party.
