I got my laptop from a store, near by there was another shop where my basic apps had been installed like MS office, Adobe etc. But now I cannot edit my Word documents. It is displayed that I have an unlicensed version. But I paid to the shop for my installation. Also I have my product key which I activated in my computer settings. But the same product key is not applicable to my MS Office 2013. Also I don't know which email id has been registered.
Kindly please help me to troubleshoot my issues.
