Windows updates Failed to install

[coucou]

Hello,
I'm running Win7 Ultimate x64 bits and Office 2013 Pro x64.
Today Windows has invited me to install the latest updates, they are 4 and all relate to Office 2013 (see image below)

After some time Windows update returns "Installation failed" Code Error: 8007006E. I have restarted the installation, Windows update returns me Failed to install "Code Error: 8007006E (see image below).

So I downloaded these update, They are .exe files

https://support.microsoft.com/kb/3191940
Https://support.microsoft.com/kb/3191935
Https://support.microsoft.com/kb/3172501
https://support.microsoft.com/kb/3191872

When I run any of these files, I have a first "Please wait while the update detection"  message and then a second message "An error occurred during the detection process" (see image below).

I'll appreciate any help
Regards
