Hi Rodion - Yes, there is a *teeny* installation required. Our FAQ states:

Run Band-in-a-Box directly from the USB drive only. This allows you to use the hard drive "as is" and run the programs from it. It requires very little free disk space on your internal hard drive. Setup will install and register the PG Music notation fonts, VSC-DXi synth, VSC-VST synth, and PG Music DirectX audio plugins on your computer, but will not install Band-in-a-Box, RealBand, RealTracks, or RealDrums on your computer's internal hard drive. You can use the programs as they are, pre-installed on the USB drive. There are shortcuts to run Band-in-a-Box and RealBand on the root level of the hard drive. Any additional programs and shortcuts are located in the "PGMusic" folder.
