When you install a program onto your computer, the program is installed onto your main hard drive. However, more people are connecting external hard drives to their computers to save space and better organise data. You may want to move a program that is installed on your main drive to your new drive. Because program installation include files that are scattered across the drive, along with registry keys that are store in your system's registry, you cannot simply "move" program files to another drive. You will have to reinstall the program onto the other drive to complete the move.
Uninstall the existing program.
Locate the software disc that you used to install the program onto your computer. Alternatively, browse to the website that you used to download the program initially.
Connect the external drive to your computer by plugging the drive's USB cable into a USB port on your computer.
Start the program installation. Insert the software disc and select the "D" drive when asked to select where to install the program.. Alternatively, download the software from the Internet and select the "D" drive as the drive to save the installer to.
Complete the installation process by following the on-screen prompts. The program will alert you when installation is complete. Restart your computer by clicking "Start," selecting the button next to "Shut Down" and clicking "Restart."
Do not disconnect the external drive while the application is running. Doing so could cause problems with your program, including data loss.
