Anaconda update broke Spyder?

Question

I launched Anaconda Launcher (Windows 7) and clicked "Refresh" next to each thing, and now Spyder is not working. An error message will appear:

---------------------------
Spyder
---------------------------
Please check Spyder installation requirements:
PyQt4 4.6+ (or PySide 1.2.0+) is required.
---------------------------
OK   
---------------------------

but this has already been done:

>conda update pyqt
Fetching package metadata: ....
# All requested packages already installed.
# packages in environment at C:\Users\Jonathan\Anaconda:
#
pyqt                      4.11.4                   py27_0

I do not understand the problem.

There seems to be a bug that Anaconda developers are working on. He was brought up here. https://groups.google.com/a/continuum.io/forum/#!msg/anaconda/DM3pbxrb_ps/llEAnH00DwAJ

Your best bet is to downgrade PyQT4 until it is fixed. Just run the following command.

conda install pyqt=4.10
