CNQMMAIN.EXE - Fatal error (CLR error:80004005)

When I start my computer I get a pop up message saying "CNQMMAIN.EXE - Fatal error  CLR eroor: 80004005   The program will now terminate".

 I only have one Net Framework installed on my computer and that is Microsoft .Net Framework 4.7.1

What is going on with this pop up

See screen shot

I have a Windows 7 SP1 with IE 11 desktop.
