This Torrent will leave you with a fully activated copy of OFFICE 2010 Professional Plus. This works for both 32-bit and 64-bit.
Just follow the instructions included :)

You shld first completely uninstall ANY PREVIOUS INSTALLATION OF OFFICE 2010 to be on the safe side.
You can do so by getting revouninstaller and uninstalling with that.
Google is ur friend for this. ;P

And btw this will be a permanent activation. I have included link to a Microsoft Tool which will show you that this is official and there is no expiration date or grace periods for this activation.
Also you can update this copy like a normal office installation.:)
Enjoy , Seed and please Comment !!
