There may also be additional requirements, such as a particular display adapter, the amount of display adapter RAM, or a permanent Internet connection to use the software. Besides the generic minimum requirements, you would also be wise to research compatibility issues before spending a lot of money on an application. For example, some applications (particularly games) have known problems with certain display adapters. When judging whether you have enough hard disk space, keep in mind that at least 15 to 20 percent of the hard disk space should be left empty to ensure best performance. Don’t assume that if your hard disk has 1 GB of space left on it, you can install an application that requires 1 GB of space. If your system barely meets the requirements in one or more aspects, the application may install, but performance may suffer. For example, the application may crash frequently, run slowly, or have poor graphic or sound performance. If you want to run an older application that is designed for a previous version of Windows, you may find the Compatibility Mode feature in Windows to be useful. This feature enables a newer version of Windows to mimic an older version selectively when it deals with an individual application. For example, an application may require a lower display resolution than Windows 10 provides; the Compatibility Mode feature can temporarily permit that lower resolution. To start the Compatibility Mode troubleshooter in 381
Windows 10, click Start and then type run programs . The Start menu will show an app called Run Programs made for previous versions of Windows. Open it and follow the directions. Some applications require an Internet connection to install them. Depending on the settings of your firewall software (such as Windows Defender Firewall), a warning may appear when the Setup program tries to access the Internet. In most cases, you can click a button to let the firewall know that it’s okay to proceed. For security purposes, it’s good to have a firewall to help protect your computer. A firewall installed on your local computer, such as Windows Defender Firewall or Norton Internet Security, is called a host-based firewall . A network- based firewall is designed to protect multiple computers on a network. Software Licensing When you buy an application, you aren’t actually buying the application. Instead, you’re buying the right to use the application in a limited way as prescribed by the licensing agreement that comes with it. Most people don’t read these licensing agreements closely, but suffice it to say that they’re pretty slanted in favor of the software manufacturer. Don’t like the terms? Too bad. No negotiation is allowed. If you don’t accept the license agreement , your only recourse is to return the software for a refund. (And good luck finding a vendor that will take back an opened box. Still, the software manufacturer is required to take it back and refund your money if you reject the licensing.) A license agreement is also called an end-user license agreement (EULA) .
