I am trying to install a Windows office Home & Student on my new laptop. Initially when i tried to install via download, it wouldn't run the setup.exe (error code 0-22). I uninstalled the office 2013 trial version which came installed with the laptop, restarted the system and then installed office (online). Then it was successfully installed. But when I try to run any of the suite products, it asks me to activate the product (again!!!) and if i try to activate it gives an error: 0xc06d007e. Please let me know how to resolve this issue. I have already wasted 2-3 hours doing this and really need office products to work on certain things.
