Adding 5.7 using MaintainanceTool corrupts my Qt installs

[stephenju]

I ran the MaintainanceTool to add the new 5.7 release to my installs. It required some updates so I let it. After restart, I added 5.7 to my Qt installs and it downloaded and tried to install it. Multiple errors occurred and I ended up with corrupted Qt installs. Repeated updates and installs didn't help. I am now trying to manually wipe the directories clean and reinstall.

This happened to my Qt installs on 1 Windows 7, 2 Windows 10, and 1 Mac machines. Not very happy about it.

Hi.
Can you describe the multiple errors?
