Qt on Visual Studio 2010 and win7 64bit

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

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

There is no Qt version assigned to this project for the x64 platform. Use the "change Qt function" function and select a valid Qt version for this platform.

Any idea how I can solve this.

AFAIK, you must create Qt yourself to get the win64 version.

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

You can also use the 32-bit platform :) A terrible way: open Qt 4.8.3 Command line and run devenv.exe : D
