@MjrWilson Wow! Typical Visual Studio. One of the many reasons I try to avoid MSVC as a compiler. I've had similar issues at work lately, installing an older win api completely ruined 3 versions of visual studio to the point of reinstalling and having to manually clean the registry. Go Microsoft! Oh well as a MSFT stock owner at least other people like them even if I don't. ;) Glad you got it fixed. :)

Tricky one ! Thanks for sharing :)

Thank you @mrjj

That tool is installed anyway. When you plan to update/modify Qt's installation then just use the online installer. That's the cleanest fastest way.

Looks like adding the use_proprietary_codecs define in .qmake.conf is not allowed by design?, i need to add these changes in order qt 5.8 to pick up the additional WEBENGINE_CONFIG : #Edit ..\qt-everywhere-opensource-src-5.8.1\qtwebengine\.qmake.conf #Add WEBENGINE_CONFIG += use_proprietary_codecs #Edit ..C:\QT-Build\qt-everywhere-opensource-src-5.8.1\qtwebengine\configure.json #Line 45 "autoDetect": false, into "autoDetect": true,

BTW, next time, please give your thread a meaningful title. Also choosing the best fitting subforum is highly appreciated. And when your problem is solved, mark the thread accordingly. We have a small visual forum guide for newcomers: Hitchhiker's Visual Guide to the Qt Forum and there is also the Forum general guide. One more thing: The image upload feature on our forum is broken, see How to insert image on this forum for a workaround. :-)

Yup, I am fully aware of that, and I have the Qt 5.5.1 version of msvc2012 in my machine. Downgrading the VS version together with downgrading the Qt version as well. The reason I am trying to use an older version of VS to compile is to allow my client to easily activate and install my application instead of going through the hassles installing the VS 2015 redistributable packages (which requires windows update on Win7 machine, else it will stuck on the Windows7_MSU_x64 installation part), and with VS2012 redistributable packages, installation will not be a problem (recent installed win 7 machine should 100% compatible with the package). But it works now for me, there are just some problems with the redistributable packages installed in my pc (2012 version) and uninstalling and reinstalled works just perfect now. Thanks!

@esope this is an unofficial extension. So you need to contact the developer directly. But manually - in the project properties - you would need to add the .lib file to projects dependencies and add the modules include path.

Why Qt 4.8.6 and not the latest Qt 4.8.7 ? I've compiled Qt 4.8.7 with VS2010, VS2013 and VS2015, in 32 and 64 bits, here's my steps: https://github.com/sandym/qt-patches/tree/master/windows/qt-4.8.7

Thanks for sharing the link !

Hi and welcome to devnet, Unless you're using an old version of Qt, the mkspec for VS2015 is already in so you can build Qt with it. As for jom, you can just call it in place of nmake. Use the full path to the exe and you should be good to go. Hope it helps

So as it turns out, compiling Qt 5.5 from git seems to solve this problem. I tried my demo program, as well as Maroon, and both display text by default (without having to set renderType to Text.NativeRendering). Dang it. That's what I get for trying a pre-release version. Thanks for the suggestion.
