Qt 4 apps on Windows are not startable from the Windows GUI

[marcel]

If you have Qt installed on the system, it will work by appending to the PATH env var $QTDIR/bin ( linux ), or %QTDIR%\bin (Windows).

Something like this:
PATH=$QTDIR/bin:$PATH

or:
PATH=%QTDIR%\bin;%PATH%

If you want to run it on another computer, the Qt libraries will have to be in the app directory.

I wonder if it would be possible to create a Qt 4 runtime installer which all people creating Qt 4 based programs can ask their users to download and install. GIMP on Windows has people download and install the GTK+ for Windows package. As more and more Qt 4 applications are developed for Windows, it becomes superfluous and increases the size of our packages to include the DLLs with each one of our applications.
