The software manufacturer will list the system requirements on the software package. If your computer system does not meet the system requirements then the software may not work correctly after installation. System requirements for operating systems will be hardware components, while other application software will list both hardware and operating system requirements.
System requirements are most commonly seen listed as minimum and recommended requirements. The minimum system requirements need to be met for the software to run at all on your system, and the recommended system requirements, if met, will offer better software usability.
