I have spent nearly two and a half hours trying to install Avast pro which I purchased on line.
I followed the instructions carefully until it came to opening the licence registration number.
The file extension is not recognised and consequently I cannot go any further in the process of installation.
After looking for support in this matter I am so angry I wish I had never heard of Avast and will not purchase a futher edition.
Trying to find help on this subject is impossible and I have been going around in circles for ages
How can I get my money back, or make a phone complaint so as to explain my dilemma ?
