Ok, thank you.

I have downloas the qt-4.4.4 snapshot but now i have another problem. I have uninstalled qt-4.4.3 and I have extracted the new version in the Qt folder. I am followind the install archive when I run the configure command I have obtained this:

Unable to detect the platform from environment. Use -platform command
nt or set the QMAKESPEC environment variable and run configure again .........................

Could you tell me how install the qt-4.4.4 becuase i didnt it with the executable version with the qt-4.4.3 and it is diferent if i download the .zip.

Kind regards.
