Arduino IDE installation awt.dll error

The objective of this short post is to explain how to solve the error opening the awt.dll file, during the installation of the Arduino IDE.

A common error that occurs when installing a new version of the Arduino IDE after uninstalling a previous one is shown below, in figure 1. The error message says that an error occurred  opening a awt.dll file for writing.

Although it is possible to ignore it and follow the installation, when we try to launch the IDE it won’t work.
