Error while installing Qt SDK 1.2.1 on Windows 7( Offline installer)

Got below error while installing.. (Don’t know how to paste an image)

“Error during installation process(com.nokia.ndk.tools.madde.usbdriver) : execution failed(Unexpected exit code: -2147418112): “C:\QtSDK\Madde\usbdriver\DPInst.exe /SE /SA /SW”“

I had to ignore this error to continue and don’t know how will this error effect my development env.

You could try and see, the name suggest that it could be somehting to do with USB, so likely if you have problems, it will be with on-device-debugging parts.
