Exasperating

I received the CD version of Tune-up utilities 2012 yesterday. I tried to install it on my PC but that stopped when entering the activation key listed on the back of the CD. I tried everything ... disable antivirus and firewall, put a space between "blocks" of letters and numbers of the data key, replaced by O 0 ... reboot the PC between each operation .. . nothing to do.
Good to know: the support telephone number provided gives you access to a service in English ... thank you very much, Madam .... Tune up for reactivity of Service by email, she finally manifested.
The only problem is that it took them a week, after a threatening stimulus, to decide to finally provide me with a valid activation key. Moreover, the speaker I had to find Tune Up seemed intolerable that I dared to revive ...
Three stars only because if the software is excellent however the support team what extremely courteous, leaves something to be desired in its reactivity. I wish you much courage if you need them.
