Was the box sealed when you received it? If not I suggest contacting Flipkart (they have a "Contact Us" at the bottom of their web pages).
Have you tried installing the software yet? I think it gives an option to install online, in which case it would then allow you to open an online account.
If in doubt call Customer Service (or use online chat) from this link: http://service.mcafee.com/faq/country.html
By the way what is the name of the software on the label?
I have never bought the software on CD so am not up to date with procedures on this but thought that they all came with an activation key from what other customers have posted.
Customer Service would know best.
If you have a CD to install the McAfee Product, you must have a 25 digit activation/product key in the purchase BOX. If you do not have one check your email that was used for the McAfee Purchase via flip kart, just to confirm if they have sent any email link for activation.
If you do not have the above, kindly contact Flip Kart first before contacting the McAfee Customer service to get this issue sorted out.
Post back if any queries
