Guild Wars and Vista

I'm participating in the Vista beta test and I want to test the game on there. I'm creating a bootable paritition for the install and I'm wondering if the license agreement will allow me to install Guild Wars on a new partition on the same system if the two partitions will not run concurrently. Any insight on this?

You can Install the GW client on as many machins as you like, since you can only use 1 at the time.

You don`t have to install GW again in different OS. Just make a shortcut pointing to your GW.exe and it will ask for a location, click ok and you`re done!
Works fine with many other games too while others require you to export a registry key and apply it to your new OS.
I haven`t reinstalled some games in years and have been running them since Win98 `till Vista

Im also beta testing Vista, i installed and run GW on it ok on Build 5384.4, i have a few crashing issuses sometimes when jumping from town to town, but thats it. About the partition, i think Mancha has answered ya question there :P
