How can i play world of warcraft on my friends computer without installing the game?

I have just installed world of warcraft at my place. 

But i want to play at a different pc when im away from home. 

Is there any way of just downloading the wow game launcher and logging in from there?

Update: Sweet, cheers guys. 

I think a large external hard drive would be a smart idea.

Best Answer:  You have to install the game onto the computer you want to play on unfortunately. There are some remote access programs out there but sadly they don't perform well enough (especially over the internet) for that to be a viable option until the technology improves more. 

The closest thing to what you're wanting to do would be to copy your entire WoW directory onto a sufficiently large flash drive (16gb+) or external hard drive and just plug it into your friends computer when you're wanting to play. I've done that in the past. If you take the flash drive option keep in mind it could be slow with loading times depending on how fast it is. 

Your best option is just to install it on all computers that you think you might play on, and it'll be there when you need it :) 

Good luck!
