Hello,

I have the Qt 4.8.2 libraries installed along with the latest version of the Qt VisualStudio addin for VS 2010. I ran a configure of all the Qt code using the x64 version of the VisualStudio x64 Win64 Command Prompt. I then rebuilt the entire Qt solution using the x64 platform in VisualStudio.

I then created a simple Qt GUI Application project in VisualStudio, which built fine in Win32. However when I try to build the same project in x64, I get the following message:

*The following error occurred.
There is no Qt version assigned to this project for platform x64.
Please use the “change Qt version” feature and choose a valid Qt version for this platform.*

For the life of me I can’t find the change Qt version feature. Can someone help me out with this because I am stuck?

Thank you.
