If this is a program; I would first download, install, and run the free edition of revo uninstaller; which should completely uninstall ALL of the program you are trying to install; including registry entries, etc. and then reboot; which will clear the system resources, etc. then try and install it again. Below is the link to revo uninstaller:
Also have a pretty bad speaker setup which is a klipsch promedia 5.1 surround speaker setup with huge subwoofer and lg blu ray player/writer. Also a hp officejet pro 8600 plus wireless all in one and a logitech s7500 webcam.
from some reason it's not showing up in the uninstaller page, and my guess is that it was never fully installed. once i got that error the installation would force quit on itself
