Comment 19 for bug 799990

> I would like to get an evironment similar to yours.
My environment takes quite a while to set up, maybe you can get away with just the problematic DLLs: http://dl.dropbox.com/u/5464702/OpenLP_incompatible_DLLs.zip
It's the iconv.dll from my ruby installation and qgenericbearer4.dll within the Qt directory structure. I have the environment variables QT4DIR and QTDIR pointing to Qt/4.7.1, and Qt/4.7.1/bin in the PATH.
But I'm not sure anymore if the environment variables are even used - OpenLP even crashes when I remove all references to my Qt build (and reboot). And I found all plugin paths also in the registry (HKEY_USERS\S-1-5-21-2378048838-1455849807-2857485230-1000\Software\Trolltech\OrganizationDefaults\Qt Factory Cache 4.7).

(My full environment is: Ruby 1.8.6 (bin directory in the PATH), Qt 4.7 for VS2008 (http://qt.nokia.com/downloads/windows-cpp-vs2008), configured for Visual Studio 2010 (witht configure.exe in the main Qt folder, something like configure -platform win32-msvc2010 I think), then compiled by executing 'qmake', then 'nmake' in the Visual Studio 2010 Command Prompt. Perhaps it would be enough to just install it and replace qgenericbearer4.dll with my one....)

I also found that the Qt search paths can be overridden with a qt.conf file: http://doc.qt.nokia.com/latest/qt-conf.html
I tried putting one into the OpenLP folder with "[Paths]\nPlugins = qt4_plugins", but nothing changed.
