Hi Im a newbie - trying to restore wallet into 2 computers

I would like to use one wallet into 2 computers, is this possible?

Im having a hard time with the wallet tutorial. Pls, help!

I was able to install and backup a new wallet on my laptop. I would like to have the same wallet installed on my desktop.
How can I do this? If I make a new installation on my desktop, its a different wallet.
Pls help! Thanks!
