I have just installed Microsoft Works and did not enter the product key. Every time I tried to open it, then it will say that I had so many times I can open it and not enter my product key. So, I finally enter the product key but after that I did enter it, and they are now asking me to install but it is already installed, do I have to reinstall it again? I can only install this to 3 computers even though I dont know how to reinstall it? Can anyone please help. Thanks.
