[SOLVED] Qt 5.3.1 broken on Windows

[Violet Giraffe]

Windows Qt 5.3.1 that I downloaded with the online installer seems broken. qmake -v shows me this:

bq. QMake version 3.0
Using Qt version 5.3.1 in c:/work/build/PADDING/lib

Where "c:/work/build/PADDING/lib" is NOT my QTDIR, it must be hardcoded somewhere in the qmake. Subsequently, qmake -tp vc -r call fails:

bq. Could not find qmake configuration file win32-msvc2013.

I assume it's because it thinks Qt is installed to that non-existent hardcoded path.

Qt Creator says this Qt version is not properly installed.

Update: it's updating from 5.3.0 that causes trouble. Removing Qt 5.3 altogether and installing it from scratch solved the issue.
