I installed successfully latest version of Qt and its working fine.
now problem is debugger , Whenever i run on debugger getting error like "unable to create debugging engine"
@PrAnit Take a look at your screenshot: there is a tab called "Qt Version" - this will show all installed Qt versions. In Kits tab you will see which Kits you have.
@PrAnit
you have - and use - a MSVC compiler, so you need Microsoft debugger (cdb) that one you'll have to get from Microsoft directly, it should come with the windows SDK packet.
