Double clicking the Drive icon does not launch the initial configuration window, the tray icon does not appear and there is no 'googledrivesync.exe' process in taskman.
I can download the application from Google themselves or and it will add all the relevant icons to my desktop. I have no problem on my work laptop running Windows 7.
The main problem is that the Google Drive desktop application does not want to launch on my Windows 7 PC. Spent some time troubleshooting with Google Support and they ended up saying 'it's a Microsoft issue, work with them'.
