I installed security center 9 from a new CD a few days ago. It is a 3 user licence and installed on one other machine with no problem. On my laptop I thought I activated it during install but the Main window says it is not activated.
I also get a popup window every time I start the computer saying I must activate within so many days (now down to 4) but nothing happens when I press the activate button. When I go to the my account web page it says I have 1 copy activated and a licence for 3 machines.
I had security center 8 installed before but the licence ran out a while ago. Also the task bar icon is red which help says means it is activated but everything else suggests it is not.
I solved my problem - I had a 3 user license disk and was trying to install from the disk on each machine. By chance I found a link on the first machine (that activated correctly) asking if I wanted to install on other computers. Pressing that link gave me a web address that installed directly on the other computers without using the install CD. If that is how it is supposed to be done then your instructions on the CD are hopeless as they make no mention of it!!
Now however I have a new problem, as of last week. Each machine in turn is asking me to verify my subscription despite the license date being december 13th 2009. Ofcourse my first computer verified correctly but the other 2 refuse - I click the verify button, it says it was verified OK, but it does not remove the error messages and my McAfee icon has a cross on it and says I am not protected.
I have now solved the issue via online help. My current program activation was getting corrupted by older McAfee products that had expired and were replaced by my new 3 user license product. Uninstalling everything, then running the McAfee Consumer Product Removal tool (MCPR.exe) to remove all 2005, 2006, 2007, 2008, and 2009 program remnants followed by a reinstall did the trick.
