It’s a standalone exe, so it runs just fine from a memory stick. 🙂
Just a quick mention of PortableApps.com, which lets you run a whole bunch of apps of a USB stick without the need for installation on a your PC.
I had a look at this a while back, but I didn’t really have much of a need for it at the time and the number of apps were limited. A colleague mentioned it today and I took another look and I’m quite impressed. The number and quality of the applications has improved a lot. Added to that, I’m travelling a lot more now so the extra security of apps on a USB stick makes me feel good. 🙂
It might be worth you taking a look if you move between machines or locations a lot.
