Why does the Qt 5.4.1 download setup target specific compiler versions?

[kito408]

Hi,

I downloaded "Qt 5.4.1 for Windows 64-bit VS 2013" setup to try it out. QT creator was able to auto detect VS2013 compiler automatically detected and used it with no issues. I wanted to switch the compiler Visual Studio 2012, but based on the file name it looks by the you need a specific Qt setup for a specific compiler version.

It was not able to find a pre built Qt5.4.1 setup for VS2012 for 64-bit. I did see a 32-bit version.

Inside QT Creator I manually created a kit and switched the compiler to VS2012 64 bit instead of VS2013, but I only have one Qt version installed which is for VS2013. There is a red ! stop icon in the QT Creator Kit dialog with the message "The compiler "... cannot produce code for the Qt version Qt 5.4.1 MSVCS2013 64bit..." I ignored the message and successfully compiled & linked a console app that runs with the VS2012 kit. I verified the compiled executable was using the VS2012 run time.

So I realize that ignoring this error message is probably not a good idea.

Is it possible to get a pre built setup for "Qt 5.4.1 for Windows 64-bit for VS 2012"? I see a 32-bit version, but I need to use the 64-bit version.
