I downloaded the online installer from the following link for RHEL 6.6:

https://www.qt.io/download-open-source/

"qt-opensource-linux-x64-5.6.2.run" and "qt-unified-linux-x64-2.0.5-online.run" got downloaded. I clicked on "qt-opensource-linux-x64-5.6.2.run" and went through the steps and I downloaded the "Tools" and "Qt-5.6.2". "Qt Creator (Community)" appears under the "Application -> Programming" but it does not respond when I click to open it.

Please let me know why this might be happening.
