qwindows.dll [copied from msvc2012\plugins\platform folder ]

where is this "msvc2012" folder?! The platform DLLs should be located in <qt-dir>/qtbase/plugins/platforms

There's also the "deployment guide":http://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html to help you with that

I've installed Qt5.1.0 SDK for MSVC12-32bit RC on my development computer. I'm not finding qtbase folder within <qt-dir>

SGaist

search for the plugins/platforms folder which should be next to bin, doc etc...

Raveendra

i found plugins/platform folder under msvc2012 folder

yes..sorry my fault. i only use the source version of Qt not the pre-compiled packages. You're right.

Raveendra

i have set the environment variable

QT_QPA_PLATFORM_PLUGIN_PATH = C:\Qt\Qt5.1.0\5.1.0-rc1\msvc2012\plugins\platforms

i meant path to qtwindows.dll

this solved my problem and exe is running fine now :)
