Alcatel OneTouch POPC7 - Need help with system updates

Hello,

I need some help with doing a system update on my Alcatel OneTouch Pop C7 (7041X). I can download the updates from the settings - About the Phone - System updates menu, but whenever I do this and try to install it I get the following error after the Phone booted into Android System Recovery:

Installing update ...
Hangouts.apk has unexpected contents
Error in Update.zip
Update.zip is not correct.
Installation aborted.

The package isn't correct huh, I did download it from the settings menu so it should be allright. I don't have a clue on what to do next, any help would be apprieciated.
My device has NOT been rooted.

Thanks in advance.
