Installed AVG 2017 free version

I just reinstalled AVG free version and want to customize settings such as scan time and all.  It does not give me that option.  I click on it and a buy now page pops up EVERY TIME.  i don't want to buy the premium AVG.  I have had AVG free for many years.  Why won't it work now?
