can ipt files created in inventor 2012 be save as a 2010 version and open in inventor

I have a ipt file created in 2012,but when i open it in another computer which only has 2010 installed,it cannot be open.when i came back to the 2012 computer,i didn't see an option to save as 2010 ipt,can anyone help me?thanks

I'm pretty sure that option is missing by design.

Cannot go backwards.

Save Copy As type STEP (*.stp) to open in old release.

can alias do this?i do not have this software and do not know what it can do
