Seems MS wormed their way into my computer and I just received the IE death knell a couple of days ago (7/2023).  I tried the solution as posted, however, the "add" and "enable" buttons are no longer visible, only "disable" shows.  Reg Edit appears to be gone as well.  My computer guru spent a couple of hours today trying to fix it and failed.  If he can't figure a way to fix it, I don't think anyone can.  How thoughtful of MS to leave me completely locked out of 15 years of personal financial information.  I don't even use IE, it's just there to make my QB program work so I can track my grocery, utility, and cat food expenses.  Anyone up for a class action????
