Karan, you mentioned that Bearer is a qt plugin. There is another thing
you could try.

Could you please check if on your win 7 is set the environment variable QT_PLUGIN__PATH?
If it is set then openlp on your system is probably trying to load qt plugins from those folders.

If so, openlp should probably unset this variable at startup.

Could you please also try to unset this variable and run openlp if it
will work on your machine?

For list of available qt variables see:

Title:
  Crash on startup because wrong Qt libs are loaded (Win 7)

Status in OpenLP - Worship Presentation Software:
  New

Bug description:
  When I first started OpenLP it crashed while the splash screen was shown - access violation in msvcr100.dll (-> Visual Studio 2010 runtime library) with some Qt DLLs above it in the callstack (according to the then attached debugger). OpenLP apparently loaded the Qt DLLs from the PATH instead of using the local ones - I've got Qt 4.7.1 built with Visual Studio 2010 in the PATH. Since the other DLLs in the OpenLP folder are linked against msvcr90.dll and runtimes can't usually be mixed this seems to be the source of the problem...
  Removing my Qt build from the PATH helps, but it would be better if OpenLP simply used the libraries installed with it.

  Using OpenLP 1.9.5 on Win 7 Professionell 32-bit
