Before purchasing or attempting to install a new program on your computer, make sure your PC has at least the minimum amount of RAM required by the program. If your computer doesn't have enough memory, the program may not run. In some cases, you can't even install the program unless your computer meets the minimum requirements. The Performance Information and Tools section of the Control Panel displays detailed information about your system, including the amount of RAM and dedicated graphics memory.
