Hi LeeMinh.
To debug mode, try with Qt5Cored.dll, Qt5Guid.dll , Qt5Widgetsd.dllRegards

Hi,
-
When you want to deploy your application, please compile it under release mode instead of debug mode.
-
You can use microsoft tool "process explorer ", to find all the dlls used in your application.

[quote author="LeeMinh" date="1374492589"]It show *icuin51.dll * is missing too after I copy 3 dll files to debug folder.[/quote]Then copy icuin51.dll into your folder.
In the link I posted, read "Creating the Application Package" -- it lists many DLLs that you need
-
"Qt relies on the ICU library for unicode support. Therefore, you must include the ICU DLLs that are located in the bin directory of your Qt installation if Qt was configured to use ICU. The Qt version bundled in the Qt5 package uses ICU, so deployment is needed there. The ICU DLLs are version dependent and have to match the ones your Qt version was linked against."- Creating the Application Package
Is it right?

From that paragraph, scroll down some more. You will see a few lists/tables of DLLs.

Dear JKSH.
Thanks for your sugesstion. There are dll files which I copy to release folder - It contain excute file.Qt5Core.dll
Qt5Gui.dll
Qt5Sql.dll
Qt5Widgets.dll
icudt51.dll
icuin51.dll
icuuc51.dll
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dllSo, I have another question. What will we do if we want to move these dll to another folder such as lib folder. I think that it will be clearly if we move these dll to a clearly name folder . It also we will not hold on it at release folder.

- You need re-read the documentation “Creating the Application Package” .
- The windows platform plugin must be deployed, it's required by all the GUI application.
- Seems that Qt5Sql.dll is deployed by yourself. so it nearly sure that database plugins is needed by your application.
- other plugins such as imageformats is required if you used .gif/.jpg/... files in your application.
- ...
- Please use a process tool such as Microsoft's process explorer to monitor your application, so you can easily find out all the dlls needed by your application.

This application has requested the Runtime to terminate it in an unusual way Please contact the application's support team for more information
May you explain it for me. I'm looking forward to receiving your msg.

Thanks,[/quote]That means your program crashed. Does it run properly on your development PC?Did you remember to include platforms\qwindows.dll?
What OS does your development PC use? What OS does your target PC use?
[quote author="LeeMinh" date="1374551835"]Will I must copy these dll - I comment above - (in C:\Qt\Qt5.1.0\5.1.0\mingw48_32\bin) to RELEASE folder?
I cant' copy them to another folder such as \MyProject\Myresources\Mylib folder?[/quote]No. If you copy them to another folder, the .exe file can't find them. In Qt, only plugin DLLs are put in subfolders.
All programs will look for DLLs in the same folder as the .exe -- that is normal. If you look inside C:\Program Files, you can see that most programs put the .dll files together with the .exe files.
If you want to be tidy and clear, put a Shortcut on your desktop.

1.It's run fine when I run it on my development PC.
2.I forgot include platforms\qwindows.dll.
3.I use win7-32bit at development PC and target PC use win7-32bit too.
I have been checking how to add platforms\qwindows.dll to my project.
Will I copy it to \release\platforms\qwindows.dll and run executable file.
It didn't work in here. Will I reconfigure something at .pro file?

1.It's run fine when I run it on my development PC.[/quote][/quote]Sorry, I wasn't clear before: Does it run properly on your development PC, outside Qt Creator? Close Qt Creator, and run your program by launching the .exe file directly.
[quote]3.I use win7-32bit at development PC and target PC use win7-32bit too.[/quote]Ok, that should be easier then. (Deployment is harder if you build on Windows 7 and transfer to Windows XP)
[quote]I have been checking how to add platforms\qwindows.dll to my project.
Will I copy it to \release\platforms\qwindows.dll and run executable file. [/quote]Yes, that is correct. Your folder should look like this:
\release\application.exe
\release\Qt5Core.dll
\release\Qt5Gui.dll
\release\Qt5Sql.dll
\release\Qt5Widgets.dll
\release\icudt51.dll
\release\icuin51.dll
\release\icuuc51.dll
\release\libgcc_s_dw2-1.dll
\release\libstdc++-6.dll
\release\libwinpthread-1.dll
\release\platforms\qwindows.dll(but maybe it needs more. Did you use "Process Explorer":http://technet.microsoft.com/en-au/sysinternals/bb896653.aspx, as suggested by 1+1=2?)

[/quote]No, the .pro file is only for compiling and linking. -

Hi,
The deployment documentation "plugins chapter":https://qt-project.org/doc/qt-5.0/qtdoc/deployment-windows.html#qt-plugins
explains that.
Basically you need to create the plugins folder and the needed subfolder like imageformats.appfolder
appfolder\plugins
appfolder\plugins\imageformats
etc...I've written a doc note with some examples about it but it has been on moderation for some time now and I can't access it.
