When using the express install command to install your driver, a percentage bar interface pops up when the system is trying to load the files from the CD or DVD. The percentage bar might stop progressing for a while and that is normal. Ensure that you do not click on the cancelcommand while this is ongoing. Also, when the found new hardware wizardinterface pops up, do not click on the next command. Ensure you also do not close the installation interface or remove the CD/DVD at any point that any of these processes are ongoing. These are some of the possibilities why your driver might stop installing.
