    Default qwt examplesdo not start

    I want to use qwt for my projects and compiled it under windows using mingw with qmake and make. Then I copied to qwt.dll to the windows directory.

    However all binaries of the examples do not load but crash with "Prozedureinsprungspunkt ... nicht gefunden in qtcore4.dll"

    Probably something was linked wrong, but what is neccessary to correct this failure.

    Add %QTDIR%\bin (eg. C:\Qt\4.3.3\bin) to PATH environment variable.

    I cannot remember any time during which Qt was installed by myself when the PATH was not set. It currently is the follwing:

    C:\Dokumente und Einstellungen\Matthias Pospiech>PATH
    PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\Programme\M inGW-Qt-4.3.2\bin;C:\Qt\4.3.
    2\bin;C:\Programme\MinGW-Qt-4.3.2\bin;C:\Qt\4.3.2\bin;

    Just notice that Qt Command Prompt automatically adjusts PATH environment variable but only for the command prompt itself. It has no effect to launching applications from file manager. See "My Computer -> Properties -> Advanced -> Environment Variables" or something like that.
