I can't download the material library. I t always stops a 268mb of 1.33gb downloaded. It has been like that the whole day. Here is the pictureof it. I hope you can help me
Installation
Hello,
When I look at your error message the first thing that comes to my mind is: Proxy settings in your browser. This is also the easiest part that may solve this issue.
If you go to the proxy settings (IE = tools menu -> Internet options -> Connections tab -> LAN settings) you get a new window, where you have to click 'advanced'.
In this window you see: Servers and Exceptions.
At Exceptions you may add (copy) the following text:
*.autodesk.com; *.google-analytics.com; *.cloudfront.net; *.virtualearth.net; *.autocadws.com; *.newrelic.com; *.akamaiedge.net; *.amazonaws.com; *.getsatisfaction.com; *.autodesk360.com; *.skyscraper.autodesk.com;
After this, try to instal Revit 2017 again.
If not you can also try the following solution that is posted about a similar issue, when stuck at downloading material library.
Would like to hear if this solved the problem.

Hi @Anonymous,
Welcome to the community!
If the above-mentioned suggestions did no resolve your issue, I can strongly refer you to THIS SOLUTION. I used this method myself before when I had issues with my content libraries - which for the life of me just did not want to install. It is something funny with the MasterXML files.
This can all be found in the link which I provided along with step-by-step instructions.
I hope this helps! 
Good day @Anonymous,

If so, please accept the relevant post as a solution so that other/future community members could benefit from it.
