Problem with mainwindow (the buttons desapear)

BrunoVinicius

I did not try exemples, but i followed some videos in youtube, and did just the same program the video shows, and give me the same error. Like you said, it does seem a bit strange.
when i reinstall the Qt, i will post the result.

Thanks!

hi again,

like you said i tried some exemples and the same error. I tried childwidget, most basic impossible!!!

I try to install some older version, but i had problem with the compiler.
i don't know what to do anymore.

Hi,

What if you use the 64 bit version of Qt ?

Also, make sure to try to disable your virus scanner for a moment to test.

Hi,

SGaist, i downloaded a Qt 5.0.2-msvc2012_64-x64-offline, but i had some problems with the compiler, because its not integrate, i assume. Do i need to desinstall my current version to install this one? And how i can configure the compiler?

mrjj, i do not have a antivirus runing in the moment, so that's is not the problem.

thanks a lot guys!!

Because that's a version for Visual Studio 2012 and you have 2013. You can't mix and match compilers on Windows, they are not compatible one with the other.

Just download the 64 bit Qt 5.5.1 for Visual Studio 2013

Hello,

i know it is not the topic problem but,
i installed Qt 5.5.1 64 (MSVC2013) version, and know in Build and Run, Qt versions and Kits configurations have problem. In compilers, the program just detect Micrsoft Visual C++ Compiler 14.0. How i configure and do i have to install another program?

Thanks

Hello again,

i reinstall Qt, using "qt-opensource-windows-x86-mingw491_opengl-5.4.0" and works properly.
Thanks anyaway guys.

Out of curiosity, did you by any chance change from Visual Studio 2013 to Visual Studio 2015 ?

Also, why install an older version of Qt and not the current ?
