This page contains information about the Windows platforms Qt is currently known to run on, with links to platform-specific notes. More information about the combinations of platforms and compilers supported by Qt can be found on the Supported Platforms page.
At the time Qt 4.7.0 was released, there were no known Vista-specific issues.

Install Qt into a subdirectory without spaces to avoid this problem.
There is a known issue with running Microsoft NetMeeting, Lotus SameTime and other applications that require screen grabbing while direct rendering is enabled. Other GL-applications may not work as expected, unless direct rendering is disabled.
