I leave here a short note, for reference.
I had trouble running the following Windows 7 Professional updates:
KB4516065 + KB4524752 + KB4535102 + optional KB4516048
All terminated in generic error. Two previous updates are required to install them:
KB4474419 and also KB4490628. To easily check if you already have these updates on your PC, I suggest you download and run WinUpdatesView v1.13 - Windows Updates History Viewer

The missing updates can be found at the following links, which point to the Microsoft Updates Catalog:
Once downloaded you can run them, in numerical order, or with double click, or right click + Open.
If all goes well, you will then be able to perform the above updates. I suggest doing them one by one.
