Hmm, I suspect very few people are going to have Visual Studio 2010
built Qt libraries sitting in their path on their Church presentation
laptops!

I don't have Visual Studio 2010, and have no plans to build Qt myself. We use PyInstaller to package up the exe, but I'm not sure I'd even know where to begin to look at how to resolve this problem. It would likely take a long time to investigate and that time might be better used elsewhere, and even then there is no guarantee we could fix it. 
However please feel free to investigate the problem yourself, since it looks like you are in the best position to do so! :)

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
