My computer was formatted and hence it requires re-installation.
Generally you have to deactivate the license before the formatting of system is done, so that you can re install the software by using the Installation kit and enter the product key by selecting the license type as SL (Software License) which can re-activate the software.
If you are using the dongle then, select HL (Hardware License) as license type then software will be activated.
If the system has already been formatted without the deactivation then, please write a mail to "support@infycons.com" so that our team will contact you.
