Qt Error
-
Everybody is good, I've come to ask a question, please answer my friends, my this period of time, met a strange question, the QT, I qtcreator perform compile and run after the pop of the following error:
This application failed to start because it could not find or load the Qt platform plugin "windows".
The application may fix this Reinstalling problem.
How to deal with?
Welcome all friends advice.
-
hi
Are you trying to run it outside Creator?
iF yes
please see

-
@mrjj Do you need me to copy the relevant documents?
If it is, I tried, but the situation is the same.
-
@jack9603301
I need to know what your are trying first.
also, if its to run out side creator
then what u have in your folder and
in your platforms folder.
-
@mrjj Could you leave a QQ, we find time to talk?
-
@jack9603301
well you should just list here what you are doing
and what files you have. :)If it says this error when inside creator, you should consider reinstalling Qt.
-
@mrjj I in using QT to engage in a senior editor, more specific details. At present, just to get the a prototype, recently for my side other things more, so this put in this period of time, now re compile the project, will offer the mistake. I have to re install a QT, but does not solve the problem.
Please give the solution, if you can, can you give me a QQ, we have the details of how to solve the problem?
If there is fate, may be in the network or in reality, become a friend.
My friends are very few and need friends, especially when I have a problem to solve.
Or you can join in (a personal project) and I need someone to help.
-
Ok, but it still not clear when this error comes. :)
When you try to run the project inside Creator?
Im not sure what a QQ is.
Its best to use forum as then all can see
and also learn or add.Also, just so u know. there is also
https://forum.qt.io/category/36/international
where you might find group for your native language if
that makes things easier.
-
@mrjj Yes, this error to be rather baffling, don't know how this happened, have failed to resolve, what can we do
-
WHEN does error happen ?
Inside Creator?
or if u click on .exe outside?
-
@mrjj said:
where you might find group for your native language if
that makes things easier.So you know my mother tongue is not English? I don't seem to have told you.
-
@jack9603301
Well my mother tongue is not english either so I might guess wrong but
some of the sentences reminds me of google translate so thats is
why I suggested it. To help you solve the problem. As same language
always help :)
-
@mrjj Error occurred through the QtCreator run, but when running the PE implementation file (*.exe) also has an error occurred
If you execute the program directly, you will tell me that you can't locate the program entry point on the DocumentManaget_d.dll.
-
@mrjj Ha ha, powerful, in fact, I am a Chinese, if there is fate, and perhaps will be friends, thank you to help me solve the problem, you say your native language is not English, so could take the liberty to ask where are you from?
-
@jack9603301
Yeah Google translate is good :) In old times no way I could talk to someone from China. Im from denmark. :) Nice to meet you.It should not give error when run from Creator.
If from outside, its OK as it need extra DLLS.Did you install from here ?
http://www.qt.io/download-open-source/
-
@mrjj Yes, I downloaded and installed from the following URL
Http://www.qt.io/download-open-source/
-
@jack9603301
Ok. is it windows 7 or 10 ?
If you use new menu and create default qt GUI project,
can this run with no errors?
-
@mrjj Win10. As you say created by default GUI if there is an error, now too late the. After a while I sleep, tomorrow afternoon I try see reply you not?
-
@jack9603301
Ok. If default clean new project also show error,
then something wrong with Qt installation.
Maybe disable Virus scanner while re-installing.
-
@mrjj Hello, I tried, to create a new project, but also the same error, how to solve?
-
@jack9603301
so even a new project cannot run from INSIDE Creator?
You must try to reinstall then.
It must work.
Also, try to disable any virus scanner when U try to run.
It might block. I have seen Avast do that.
-
@mrjj Disable all virus scanner and HIPS system and then re install?
-
Yes, as something must go wrong as
it should NOT give such error when run IN creator.
So maybe scanner takes a DLL while installing.
Also try to run a project with scanner off.
-
@mrjj Thank you, thank you for your help. Very glad to know you, I try to see, I hope to have the opportunity to communicate with you after a lot of.
-
@jack9603301
I cross fingers :)
Well you can often find me on the forum :)
-
@mrjj Thank you
-
@jack9603301
Just to be sure, you do use the
" Qt Online Installer for Windows"
exe file to install?
-
-
@mrjj I generally use the off-line method, a separate installation, of course, the installation directory is the same directory to cover the way
-
@jack9603301
ok so one of these?
Qt 5.5.1 for Windows 64-bit (VS 2013, 823 MB) (info)
Qt 5.5.1 for Windows 32-bit (VS 2013, 804 MB) (info)

-
@mrjj Online installation is always a failure.
Online installation is not a failure for a long time.
-
@jack9603301
Those are offline installers.

@mrjj Qt 5.5.1 for Windows 64-bit (VS 2013, 823 MB) (info)

-
@jack9603301
Yes, which one did you use?
-
@mrjj I listed the same installation at the same time.
-
@jack9603301
do you use VS 2013 or MinGW?
-
@mrjj In fact, at the same time useful, CL often reported CL error, MinGW may be more commonly used now
-
@jack9603301
well try with mingw then.
-
@mrjj what do you mean
-
@jack9603301
if you dont need to use visual studio (which you must also install)
then try the
Qt 5.5.1 for Windows 32-bit (MinGW 4.9.2, 1.0 GB) (info)
one as it normally just works.
