At the moment run the whole lot off the flash drive and then on the day you are going to go live copy the files onto the laptop, this is sort of how I do mine.
I have my Vixen on my flash drive so that I can have a bit of a fiddle at work, or at home in the house or out in the garage on the lights computer. When I am ready to go live I will just copy the folder off the flash drive onto the lights computer.

Sandy, keep it all in a directory/folder called Vixen or whatever with all your sub directories in that and then you can move it around to your hearts content. Just run the vixen.exe file from the folder. Have a try and you will see what I mean.
What you will need to do though is, when you are ready to go live, setup the correct path to vixen so that it starts up when if your computer reboots.
