Material library wont install Corona 8

Material library wont install Corona 8
Any suggestions?

Hi, what exactly is happening? Is there some error message? Nothing happens if you press the toolbar button, or…?

I have the same.

Removing previous installation of Material Library… done
Installing Material Library… Failed to download additional installer data (MaterialLibrary): Failed to send GET request to https://installer.corona-renderer.com/3dsmax/8/MaterialLibrary
Error: Połączenie z serwerem odwołań było niemożliwe lub nie można było uzyskać ostatecznej odpowiedzi.
Unpacking and installing…

Installation finished

Edit:
Ok it worked. I installed the libraries manually.
You need to download them from the link https://installer.corona-renderer.com/3dsmax/8/MaterialLibrary.
Then copy them to the folder with the universal installer file. Open installer and update.

what “Arthi76” said happend to me.

You need to put Material Library file to the same folder with installer file (corona-8-3dsmax.exe) and run it one more time.
