Because of some missing module, I uninstalled, and reinstalled, Python and all related packages.

Now, some programs that formerly worked, now do not.

I see that there is a PyQt4 under site-packages, with a long list of files, as well as a sub-directory, Qwt5, which also has a list of files.

Under Python27, there is another PyQt4 with no list of files, but a sub-directory, Qwt5, which contains the same file list as the other Qwt5.

The packages were installed by PyQt-Py2.7-x86-gpl-4.9.6-1.exe and PyQt4.Qwt5-5.2.1.win32-py27.exe.

Is it possible that this is wrong, and is the cause of my problems?
