I've recently deinstalled Qt 5.6, removed possible leftover directories and installed the newest version 5.7 (Version: Visual Studio 2015 - 64bit)
Expecting to hit a few difficulties, I had an issue right away, which I got fixed after deleting the toolchains.xml file as suggested in this post.

Now my problem is, that when trying to execute the code in debug mode - debug it (default hotkey F5) - I get instantly a very descriptive error.
"Unexpected CDB Exit"
"The CDB process terminated."
Running it works fine, debugging not at all.

I have a totally empty project (default files) without changes - Qt Widgets.

I went through previous posts and google and don't seem to figure out a solution for this error.

I hope someone's able to help me with this issue.
