One of my 4 multi machine updates had a glitch in downloading and said something was wrong with the connection--try again later.  
There is nothing wrong with my internet connection,  just this hang up that cannot be corrected.  
I understand that removing the old software was part of installing the new software therefore a removal program must be available.  I think that is what I want. 
 Other sources say to totally remove the corrupted version on the machine where it happened and re-install from scratch.  
Also my expiration date did not update.  Two computers updated with a some  trouble, but they  updated.  
My main computer is FUBAR  all related to the download.
