This is my fifth attempt to post a response. I will try using the paste command in the command section above. I went to the link you gave me. The link information mentioned problems with PC's that had been upgraded from Windows 8.1 to 10 which is true for my PC. I uninstalled Anti-Exploit, then restarted my PC, then I downloaded the setup from the place you linked me to. I installed Anti-Exploit. It now works fine. The problem with my inability to open Edge is gone. And there appear to be no other problems. Michael, Your reply addressed my concern that I did not get the free version, but a trial of the premium version. I understand your reply that the version will revert to the free version if I don't make payment. That eliminates my concern about getting the wrong version. Again, thank you both for your help. My problems appear to be solved.
