Making changes or installing Sage seems like a simple task. Select install. Wait a few minutes. Start working.
That is how it is supposed to be.
In real office settings there is a chance that it doesn't work as easily. Something becomes stuck. The error message seems to be completely unreal. Or worse, Sage installs flawlessly, but it fails for it to be opened properly afterward.
A majority of people do not mess things up in a deliberate way. The issues usually stem from little things that no one ever tells you about.
Let's take this in simple terms.
sage support (check out this site) is not like the kind of app that you download and then forget about.
