You'll probably find it easy to install most of today's software yourself - suppliers have gone to a lot of trouble to streamline and automate the installation process. However, that isn't always true, particularly with software that is more technical in its application. For instance, I recently needed to update the display drivers on my PC. The supplier's automated install process didn't work, but I was able to work around this problem.
If you need to install or upgrade software on your PC and you don't feel confident about doing it yourself, call me to arrange a visit and I'll do it for you. I'll also configure it to meet your requirements and show you how to run it.
