I am a computer scientist and I have been an ESET customer for 20 years never had any problems until today I updated my antivirus without problems but when I did the same thing with my friends, who had decided to buy it via Amazon, I had problems with the code in fact, once entered it gives me error ACT-25, In their case I activated the TRY function and re-entered the activation code, but always the same.
On other occasions he would give me the message, "MAXIMUM NUMBER OF LICENSES EXCEEDED" but it was the first one made after opening a new package.
WHAT SHOULD I DO?
