    I've tried downloading both the online (qt-unified-windows-x86-3.0.6-online.exe) and offline (qt-opensource-windows-x86-5.12.0.exe) installers.
    Whenever i run them (as administrator), my cursor changes to the loading symbol for a split second, and returns to normal. Running through command line gives the same results, with no message. Disabling antivirus and firewall, and restarting the computer gave no results.
    Any help would be appreciated.

          Hi, netutils.dll is a normal Windows file, perhaps it's broken, you could try a scan: open a CMD window as administrator and type:
          sfc /scannow

            Tried sfc, no errors found.
            Also tried registering the dll, which gave me an error, saying .dll was loaded, but the DllRegisterServer entry point was not found. Apparently that's what happens when the .dll isn't COM

              What is happeneing then actually? Is it hanging or crashing?

                Another approach that's worked for me when Windows 10 gives me lemons (like in your case when the app just exits), is to create a brand new user, switch and log in to that account. Then you will have a fresh desktop (and presumably a healthier registry), try installing Qt for that user.
