Boot2Qt devices are not detected in Qt Creator 3.6.1 on Windows

I am setting up a FreeScale i.MX6 series SABRE board by following the instructions given at http://doc.qt.io/QtForDeviceCreation/qtee-preparing-hardware-imx6sabresd.html. Everything worked fine until I reached the step of Configuring a Device Kit in Qt Creator. The SABRE i.MX6 board was not detected. In Tools->Options->Devices, the board wasn't displayed in the combo box. The following messages were displayed in the General Messages tab when the Qt Creator launched:

Checking for license updates ...
Checking for updated license succeeded (1 licenses fetched)
Boot2Qt: adb server started.
Boot2Qt: Connected to adb server.
Boot2Qt: Retrieving platform info. Full command line is 'C:\Program Files (x86)\Android\android-sdk\platform-tools\adb.exe s b2qt<device type>-<serial no.> shell "appcontroller --show-platform && appcontroller --version"'.
Boot2Qt: Platform retrieval failed for device with serial number ' b2qt-<device type>-<serial no.>': Failed to start adb..
Assuming it is not a Boot2Qt device.

The command of 'C:\Program Files (x86)\Android\android-sdk\platform-tools\adb.exe s b2qt<device type>-<serial no.> shell "appcontroller --show-platform && appcontroller --version"" failed to run. It appears that the path of the adb.exe file containing spaces causes the adb failed to start. After I reinstalled the Android SDK Tools and gave the installation path without any spaces in it, the command ran successfully. The board was detected as a Boot2Qt device.

I installed Qt Creator 3.6.1 using the Qt online installer v2.0.3.
