Qt on Visual Studio 2010 and win7 64bit

Question

I decided to start working with Qt on my win7 (64bit). I downloaded and installed qt-win-opensource-4.8.4-vs2010.exe and the qt-vs-addin-1.1.11-opensource.exe.

Now I can nun Qt projects on Win32, but I want or I need them on Win64 mode. When I try this I get this error message

there's no Qt version assigned to this project for platform x64 Please use the 'change the Qt version' feature and choose a valid Qt version for this platform.

Any idea how can I solve this.

Answer 1

If you want to build 64 bit code, you need to build Qt manually 64 bit version. qt-win-opensource-4.8.4-vs2010.exe only 32 bit.

Also you can use 32bit platform :) Ugly way is: open Qt 4.8.3 Command Prompt and run devenv.exe :D

Answer 2

AFAIK, you have to build Qt yourself to get a win64 version.
