microsoft office help

I have got me laptop but when i go to do anything on it microsoft office is asking me to register

with the authenticity key code which i cant find anywhere, the version i have got is on a 60day trial

so my question is , short of going back to the shop can anybody point me in the right direction of where to find a keycode? or any other way round this?

thanks

Get someone to give you a Corporate version (Volume Licence Version) it does not need activation but does need a code.

Which version is it?
