When i install corona renderer 7 and when i use it, the corona material library does not appear. when i click on it, it tells me that corona material library is not installed. i have already tried to reinstall it several times and i cannot solve the problem. thanks.
Please try installing the Material Library manually as explained here:

After a successful installation it should appear in C:\Program Files\Corona\materials
Let me know if it still doesn’t work.
it totally works, thank you very much.
