UE4 freeze after double clicking or editing constant 3 vectors

Hi Eric,
I 've made the maximum of c++ updates i could do. Some of them couldn’t install because it said that visual need to be install on my system to run these updates. Do I need Visual to run the engine?
After that I restarted my OS and then verify the engine before running it.
Finaly I started the engine and I still have the same problem.
I made a little research on how to use winows envent viewer.
I started it after my freezing. I’m not 100% sure to have done what you asked me to do because all of these is a little bit chinese for me…
I opened some of the errors (I could not find one with the same time the freeze happened) and I copy pasted it to a text file. Then I ziped the files as you told me.link text
