Ok. I have the installer talking to the phone. I have created a folder "c:\platform-tools" which contains adb and fastboot etc from google. I have copied the installer into the same directory and added the directory to PATH enviroment variable.
Now when I run the installer it works as expected until I run up against a bug.
The install now fails with an "Adb push error". I found the install log and the reason the push fails is because of a forward slash in the file name. I found the bug report and commit expected to fix it. I guess I'll have to wait until the next release of the installer.
