LyX ⇒ Some errors/warnings during the installation of Lyx

[l3gi0n]

I have MiKTeX installed and I am installing Lyx on Windows 10, During the installation MiKTeX asks to install a lot of packages and I install them one by one....However, when I click "Show Details" during the installation, there are some errors, warnings and other things that I want to understand, here is what happens:

I get lines like these:

Code: Select all

+checking for package a0poster [a0poster]... no
+checking for package accents [accents]... yes

I installed all the packages that MikTeX asked me to install, what does no and yes mean here ? does "no" mean that MiKTeX does not have the package ?

I also get :

Code: Select all

miktex-maketfm: security risk: running with elevated privileges
miktex-makemf: security risk: running with elevated privileges
miktex-hbf2gf: security risk: running with elevated privileges

What do these mean ?

I also get errors like this:

Code: Select all

Sorry, but miktex-makemf did not succeed.

The log file hopefully contains the information to get MiKTeX going again:

  C:\Users\Amir\AppData\Local\MiKTeX\miktex\log\miktex-makemf.log
miktex-hbf2gf: security risk: running with elevated privileges
Couldn't open `rzm.cfg'

hbf2gf (CJK ver. 4.8.4)

Here is what the installer says when clicking "Show Details" it is NOT complete though, I copy/pasted it before the installation was fully finished : https://pastebin.com/CxTNcL7J

Did I install Lyx correctly ? Are these errors important ? Can you please tell me if there is a fix ?
