Many companies draw the line to who can install software onto their computers which could be the result of many different reasons. One of the most common reasons is that someone could get a virus if they install a dodgy piece of software. Another reason maybe the uncheck that no-one in a work orientated business is installing something that is not work orientated.
Before installing and updating software I checked both the requirements and limitations. I also made sure that all of the legal agreements were met before I installed the software as well as making sure that updates of the software are legal.
