Error Cannot complete the request on MAC

I recently downloaded the Eclipse software, from the official website as a tar.gz file. I ran the software on m MAC machine and installed it.
I was working with it without any error message. Now when I want to update the software I keep getting error messages.
I click on help – Check for updates and I get the following error message:
Software Updates
Cannot complete the request. This installation has not been configured properly for Software Updates.
Is this error a common one? Can someone help me with the same?
