Qt 5.1 Installation Hangs in Windows 7



  • Early this week I downloaded this version of Qt 5.1 for Windows 7 to my home desktop and tried to install it:

    http://download.qt-project.org/official_releases/qt/5.1/5.1.0/qt-windows-opensource-5.1.0-msvc2012_opengl-x86_64-offline.exe

    After a short time the install window appeared and quickly displayed a message like "Installation 34% complete". This window stayed put for 3 days until I cancelled the installation.

    Any reason why the installation might hang up, or hang up for so long?

    The only issue I see is the possibility of installing a 64 bit build on a 32 bit windows in case you have only a 32 bit windows version. Not sure, if this would matter though.

    Did you retry including the complete download?

    That is probably the best thing you can do.



  • My system is 64 bit, and that's why I tried to install the 64 bit Qt version.

    By "retry", I take it you mean download the .exe again and try installing that?

    Thanks.

    Yes, that is what I mean with retry.

    You do not need to use the 64 bit version necessarily because you have a 64 bit windows. On 64 bit windows you can also install the 32 bit versions. I am not completely sure if it will work the other way around.

    If there is no need for you at the moment to use the 64 bit build, you can also start with a 32 bit build. Typically people are making the decision on the compiler they have respectively they want to use.

    In case the second try of installing the 64 bit fails again (including the download), I would rather go for a 32 bit version.



  • Ok, I'll try that.

    I have no idea if I "need" a 64 bit build, because I'm a rank newbie with Qt and just want to get something installed to go through the beginner tutorials, and to see if Qt is what I want for some long term projects.

    I don't have a compiler installed on Windows 7 (I'm a Unix guy, really) at this point, so I really am at square one. Any suggestions on a compiler that works well with Qt?

    I have Cygwin installed, and all the GNU compiler stuff, but I somehow think that that won't help with Qt and Windows 7.

    Well, you can go for the "MinGW":http://download.qt-project.org/official_releases/qt/5.1/5.1.0/qt-windows-opensource-5.1.0-mingw48_opengl-x86-offline.exe option than. MinGW is the windows port of gcc. Since you might already have used this compiler on Linux.
    The 32 bit stuff is for a beginner as good as any other one. When starting it is typically not required to have the full blown stuff. I am using a 64 bit self compiled Qt 4.8 version, but this was merely for getting in touch with 64 bit than a need by the application. And my applications are already a bit bigger.



  • Ok, downloading Qt again and reinstalling worked this time.

    The first time around I downloaded the Windows version with OpenGL. The second time I used the version without OpenGL.

    Thanks for the suggestsions!
