I decided to add one more compiler to my Qt 5.10.1. I started MaintenanceTool.exe from the folder in which Qt lies.

I myself am not registered with qt corporation.

In general, I pressed further, further.

Brought me the inscription in red "You need at least one valid repository to complete."

Read here as a repository to connect. But for some reason, he writes the error "Failed to open the Updates.xml file for reading: No file name specified"

How to add component?

Is registration required in qt corporation?

    No registration is required. You apparently installed Qt via the offline installer, for offline updating via the Internet does not work, in order for the update to work, you must install Qt online installer. https://www.qt.io/download-qt-installer
