I have just tried to update iTunes 32 bit, and Java Runtime Environment 8 (32 bit), and both updates have failed. I have Windows 7. I don’t know what to do next, and would be grateful for some help.
Update them directly from the websites.
Try Resetting the Updater database:
For Avast2014 go to “Settings” > “Tools” > “Customize” Software Update > “Database Reset (troubleshooting)” and do a “reset”. Doing this should bring programs needing an update to the top of the list (if they weren’t already).
In the event you’re using Avast2015: Resetting the internal database of the Software Updater
I had to look this up because I use Avast2014 (which is different than 2015 regarding the “reset”) and WILL NOT go to a version that has a “shopping cart” tab (unbelievable) but AFTER 15+ YEARS will finally find Virus protection elsewhere if this doesn’t change and 2014 is no longer supported. First we get “advertizing” popups that cannot be disabled in the “free” version which is bad enough, now we have a “shopping cart” in version 2015, REALLY, just WOW. If Avast doesn’t wise up and realize that people do not need to be continually prompted to add module options all the time I’m thinking they will lose business as I know of AV programs that do just a good a job or better without all the bombardment of ads. What Avast ought to do if they feel a need to “advertize” their products to their users is after 10 years as a customer for example to allow these annoying adds to be “turned off”, after all a user with them this long is well aware of the products available to them. Now I feel better getting that off my chest regarding version 2015 
P.S. I’ll put in my 2-cents every time I get a chance (since Avast doesn’t seem to care or get the message) regarding the annoying popup ads considering that I’m a very very long time user that is frankly getting fed up and will eventually move on if things don’t change with Avast regarding this harassment crap. The powers that be might consider putting in place “learning” software that eventually “gets the message” if popup ads are ignored long enough (it’s not like users aren’t aware of the products available to them after all).
