It's only this file, you can put it where ever you want, all you have to to is click on the midi power exe file. if you just can't figure out how to get it to work, just goto ftp://209.186.13.74/pub/midipower.zip. this is the file that contains the installer / uninstaller. I didn't see a need for an installer and uninstaller since it was only this one small file. YOu could just as easly just copy the file to your desktop and use it from there, it wouldn't hurt anything (as far as I know :) )
