Any problems with a 64-bit Qt Designer would be reflected in problems
with Qt and PyQt. In other words, if your PyQt installation is working
fine with your Qt installation then the problem may be elsewhere.

Nothing about those particular versions immediately springs to mind.

It may depend on how Qt Designer was built and on the PyQt modules that
your IT department has provided.

If Qt Designer is built statically then you won't be able to add plugins.
Are there any C++ plugins installed? You can check by opening the Help
menu and selecting the "About Plugins" item.

If you start Python at the command line and type

  from PyQt4 import QtDesigner

what do you get? If this module isn't available then that's one reason
why Python plugins aren't working.

That's all I can think of right now.
