Installing the full qt 4.8.6 sdk
-
Hi @amirlevi, and welcome to the Qt Dev Net! May I suggest installing Qt 4.8.7 instead? It is the same as Qt 4.8.6, but with lots of bug fixes and performance improvements. You can find the link at http://download.qt.io/official_releases/qt/4.8/4.8.7/
(What's more, if you are starting a brand new project, it's best to start with Qt 5.7.0 because Qt 4.8 reached end-of-life in December 2015 -- you can get it from https://www.qt.io/download-open-source/ )

If you wish to use Qt 4.8.6, you can find it at http://download.qt.io/official_releases/qt/4.8/4.8.6/
But once again, Qt 4.8.7 is backwards compatible with Qt 4.8.6
