If you are wanting to change where the Driver is installed on your system you can do that on the first screen of the driver install.

This will be the first window displayed when you open the driver install file. If you are wanting to change the drive that our driver is installed on, you will want to start by using the button marked 'Custom' in the bottom right.
In this window you will see the default drive selected. To change the install path, you can type in the box or use the 'Browse' button to select the install path of the driver.
Once you select the drive that you want to install to, you can go ahead and install the driver.
