running Qt application on computer without Qt

[vonCZ]

To simplify things: I used the following .pro file

################################################## ####################
# Automatically generated by qmake (2.01a) Tue May 29 23:32:12 2007
################################################## ####################

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

# Input
HEADERS += dialog.h
SOURCES += dialog.cpp main.cpp

to create a Visual Studio project using qmake (WindowsXP). This is the simple "basic layout" Qt demo that comes with the Qt installation. It compiles/runs fine, but when I copy

basiclayout.exe (release version)
QtCore4.dll
QtGui4.dll

to a directory on another computer that doesn't have Qt installed and try to run it, I get error:

The Application failed to start because the application configuration is incorrect.

What am I missing?

Is this Visual Studio 2005? If so, you may need to copy over the manifest file as well. (Just a guess). Look at the page on deploying under Windows in assistant for more information.

Thanks Brandybuck, Assistant was helpful. I'm actually using Visual Studio 2005 Express and have discovered from both the Assistant documentation and web searches: deploying Qt (or other) applications built with Express isn't easy. I've gotta put it aside for a few hours now and work on something else, though. Hopefully I'll get it later today.
