3. Installing a New Program
• Can install programs from number of different sources
• Some programs automatically start install when you insert disc
• Programs from Internet fall into one of two categories:
– Download program file for installation
– Subscribe to SaaS option with software vendor
– Both entitle you to updates
• Allowed to make one backup or copy of original
• If downloading software from Internet, always save it and scan for
viruses prior to installing
• When software vendor notifies of updates to program, these updates
usually are not critical to install immediately
– Be sure to read notice to decide whether to install
– Might receive notices from vendor in e-mail, media, or link

4. Why Isn’t the Program Working?
• If unable to install or download program, may not have rights with your
user account
• If have rights but installation stops and error message displays, there
may be some kind of defect or damage to program copy
• If using backup copy and installation does not start, try install from
original media
• Installation can also fail with hardware conflicts
• Software conflicts also very common reason for installation to fail
• If installation successful but you cannot access existing files in new
program, check if new program has tools to convert files from earlier
format into new program
• If software installation was successful but having problems viewing
different parts of the program, check system requirements
