Qt Creator cannot load 'Help'

kqt-mr-nv6

I have just uninstalled Qt 5.1.1 and installed Qt5.2 beta-1 on windows-xp
when I start the QtCreator, a pop-up window gets displayed showing error message
_
The following plugins have errors and cannot be loaded
Help
Details:
C:\Qt\Qt5.2.0\Tools\QtCreator\lib\qtcreator\plugins\QtProject\Help.dll: Cannot load library C:/Qt/Qt5.2.0/Tools/QtCreator/lib/qtcreator/plugins/QtProject/Help.dll: The specified procedure could not be found.

I am unable to view any help/Qt Reference doc

I have solved this problem.
Execute the command:locate udev.so
if you get
/lib/i386-linux-gnu/libudev.so.1
/lib/i386-linux-gnu/libudev.so.1.3.5
then
sudo ln -s /lib/i386-linux-gnu/libudev.so.1 /lib/i386-linux-gnu/libudev.so.0

so it is ok
