Hi and welcome. I'm Ansh and today, I will be trying my best to solve your issue.
Please answer this in yes or no(do not type your product code here): Do you have the product key with you?
ok, it should be printed on your disk or the cd cover
without the key, you will not be able to install it
That is not the key
It should be a 25 digit code
And pls do not type it here
Just try finding it
I will be waiting
Are you there?
