Why Do Errors Happen? 

There's actually a number of reasons why these annoying errors happen, but the most common are caused by new programs getting installed on top of older programs before the older versions are completely removed. 


When this happens it causes registry pile ups, displaying to you a possible 'error message' so you can repair it quickly before more malfunctions happen. Another reason, is damage that's been done by spyware programs, or even viruses wrecking havoc and deleting important files.
