The Qt version is invalid

'm trying to make a new project using Qt Creator, and I get the foll开发者_C百科owing errors when compiling:

The Qt version is invalid: Could not determine the path to the binaries of the Qt installation, maybe the qmake path is wrong?

The qmake command "<not found>" was not found or is not executable.

How can I solve this issue?

Thanks.

Issue solved.

I added this to PATH: C:\Qt\2010.05\qt\bin

Instead of: C:\Qt\2010.05\bin

As that later didn't contain qmake.exe

Thanks.
