Windows - Missing Media Feature Pack

After some research it seems these media packs are very win version dependent. Information that is not so clear. For instance i run a Pro N edition and there seem to be a different package to download dependent on where what your windows version is right now. I don't really understand why Microsoft can bundle this or make the executable just download the right version for my Windows version. And when installing the package on wrong version it says its successful but its really not.

Last One is extremely important and will be the solution to your problem KB3133719:

EpiServer - HTTP Error 403.14 - Forbidden - Solution

This is very common and can lead to unnecessary frustration.
Basically if no html page is received when trying to call a page it end up being handled as "no access".
So in EPisevers case this often means the site is probably actually working fine.
To fix this just append /episerver to the path and you can probably login then add the host name in
Administrator / Websites hostnames. And it will start working.

Node - Bind Node or Gulp to System Path

Common error in this case:

'gulp' is not recognized as an internal or external command, operable program or batch file.
Solution:

PATH=%PATH%;C:\Users\**<username>**\AppData\Roaming\npm

Node Sass could not find a binding for your current environment :

Solution:

> npm rebuild node-sass

First Time or If the project has added NPM run:

npm install

npm install gulp -g

Möjligen också installera yarn.

Kör Remember:

Vid Deploy: Skriv: yarn run build 

Vid Test: Skriv:  yarn run dev

NO gulp command found: If nothing works  reinstall nodejs and then reinstall with gulp. However gulp doesnt support the new nodejs so NVM needs to set older version.

This can be done with the following code in SASS:

   ol li:before {  
     content: counter(li)". ";  
     counter-increment: li;  
     position: absolute;  
     left: 0;  
     top: 0;  
     margin: 0 0 0 -7px;  
     width: auto;  
     height: auto;  
     font-weight: bold;  
     color: orange;  
   }
