I have a QtQuick application based on Qt5.1 that starts on my machine (developer-WIN7) and on another (client-WIN8) machine but not on another client(WIN7) (there is no errors) ?

the previous version of my app which uses Qt5.0.2 works good on the same client.

Have you an idea of what the problem is how can i find the problem ?

Thank you.

Edit: I have deleted the grafic driver and the application is opened but there is a blank screen.

  • Which OS? Which platform? Are you correctly following the deployment manual? Less information you give, less are the chances of getting a good reply... – peppe Jun 27 '13 at 16:15
  • The client machine on that the application works has a Windows 8 OS and the second machine on that it don't work has Windows 7 as OS. – Slim Jun 27 '13 at 16:27
  • @peppe i follow the same instructions as for Qt5.0.2 version. – Slim Jun 27 '13 at 16:28
  • I have made some tests and after deleting the grafic card driver it works but there is a blank screen. – Slim Jun 27 '13 at 17:13
  • Are you using the OpenGL build of Qt, and the target machine is missing OpenGL drivers? – peppe Jun 27 '13 at 21:11
  • @peppe. I think that i'm using the OpenGL build of Qt. Here is the installation file name : **"qt-windows-opensource-5.1.0-rc1-mingw48_opengl-x86-offline.exe"** what should i do ? The grafic card of the other machine is : **Mobil Intel(R) 945 Express Chipset Family**. Thank you. – Slim Jun 27 '13 at 22:12
  • I have the strong, bad feeling that you don't have OpenGL 2/3 support with such a card, only Direct3D 9/10. Therefore, please try using the ANGLE build of Qt (i.e. the one *not* marked with OpenGL). – peppe Jun 27 '13 at 22:16
  • @peppe. i searched for a non OpenGL build but i don't find one for the Qt5.1 version. – Slim Jun 27 '13 at 22:28
  • The RC2 should be out any moment soon, maybe a ANGLE+MinGW build will be there. Otherwise, please try compiling from sources. – peppe Jun 28 '13 at 07:26
  • @peppe. Thank you for all this responses. Now i know what the problem is. I need that working version for tomorrow. Could you advice me on how to do this compilation ? – Slim Jun 28 '13 at 14:58
  • I have some new things related to this question. Should i create a new question ? – Slim Jun 29 '13 at 12:46
  • @peppe. I have used the non-opengl (angle) msvc 2012 version and it works now. Thank you. – Slim Jun 29 '13 at 13:40
