Hi Tech and others.
Soon after my last post and in desperation. I got the usual notice “pepairing to install”.
It stayed like that for one hour. HD stationary.
We had to out so I left the Laptop on and disconnected the cat cable.
On return 3 hours latter the same notice was on screen. I clicked the X and another warning notice came on screen in red. Two others were behind this one. One, believe it or not, was an invitation to insert the Key which I did then a rapid change of screens occurred. Finally saying that Avast was successfully installed !!
The only thing that I can think that was different in some part of my fumbling was that I had uninstalled in safe mode. As you recommended.
Alls well that ends well. I have the orange rotating ball and it updates smoothly, with vocal notification. All buttons are active.
Thanks for your patience, I nearly gave up.
