Cannot import PyQt4.QtGui
Solution 1:
Add the the PyQt4 directory containing Qt's applications and DLLs to your PATH environment variable. In PowerShell, provided you didn't change any of your install paths, that'd be
$env:path += ';C:\Python26\Lib\site-packages\PyQt4\bin'
Solution 2:
I found a solution on another forum that worked for me. I needed to copy QtGui4.dll and QtCore4.dll into the ...\Python2.7.1\Lib\site-packages\PyQt4 directory. Note, I left the original in the bin directory.
