Install QT Creator - failed to start - it could not load Qt Platform

[peter_cz]

online installer

@peter_cz Try to start QtCreator from a cmd.exe after setting "set QT_DEBUG_PLUGINS=1" there. Then you should see a lot of debug output which could help to find out what is going wrong.

[peter_cz]

I did:

cd C:\Qt\Tools\QtCreator\bin>

set variable as

C:\Qt\Tools\QtCreator\bin>set QT_DEBUG_PLUGINS=1

run creator as
C:\Qt\Tools\QtCreator\bin>qtcreator.exe

and no debug info and imedatelly Error message appears

BTW is it possible to include image to this forum as screenshot from my PC ?

@peter_cz My bad - release build will probably not show anything.
Image sharing is working only sporadically here. You can try.

What do I need to do to make it working on Windows 7 and supply info you need to resolve the issue?

@peter_cz
Its pretty odd to have creator say so.
Normally its with deployment of apps.
do you use mingw or visual stud?
It could be the vs runtimes as they are not always installed in win 7

I would look at Creator.exe with
http://www.dependencywalker.com/

and see if something is missing.

Maybe install was damaged
Check your creator have the actual dll

Mine directory looks like this

Hi
It does look ok
And it seems that all Qt*.dlls can be loaded?

I wonder if something went wrong during install.

The installer didn't say anything?

Hi, you could try once again with set QT_DEBUG_PLUGINS=1 but this time, before you start qtcreator.exe, to see the debug output, download and start dbgview.exe

please look at this thread about Application can't start because could not find or load Qt
