Many people want to install our software onto a USB drive so that they can use it without having to install it on the computer they are sitting at, (either because IT policies don't allow them to install software, or as a way to save time.) Logger Pro and Logger Lite require drivers to communicate with the hardware and without those drivers installed the program can crash or give error messages.
However, Graphical Analysis 3.8.4 doesn't need any drivers and can be installed and run from a flash drive or network location easily. You need at least one computer where you can install the program, and then copy the "Graphical Analysis 3" folder, (from C:\Program Files\Vernier Software\ or C:\Program Files (x86)\Vernier Software\ on the computer where you installed it) onto a flash drive/network location. Then when you want to run the program, go to your flash drive and go into the Graphical Analysis 3 folder, and run the program GraphicalAnalysis.exe Note that Graphical Analysis can open and save both Logger Pro and Logger Lite files, but can not directly collect sensor data.
