I cannot install internet explorer 11 in Windows 7 Pro 64-bit. I downloaded IE11-Windows6.1-x64-en-us.exe from Microsoft's web site, and it starts the install, but immediately comes up with the error message "Internet Explorer did not finish installing". I have turned off my Anti-virus program, scanned for infections with Malwarebytes (found none), and tried "System Restore", but nothing helps. I presently have Internet Explorer 8, because I have always used Google Chrome in the past. Any help would be greatly appreciated.
