To deploy Google Drive, you want to download the file gsync.msi. To get this file you need to know the version of gsync to work out the URL. e.g. version 1.22.9403.223 uses the URL http://dl.google.com/drive/1.22.9403.0223/gsync.msi. Note how the extra '0' has been added to '223'. If you try to use http://dl.google.com/drive/1.22.9403.223/gsync.msi you'll get page not found. This extra '0' is needed to make the last group of numbers up to a length of 4.

New versions of Google Drive are released ever two weeks or so so to save my time I run a task schedule on a PC that runs every day, sees if there's a new msi, downloads it and makes a new WPKG XML file. To do this I run a compiled Autoit script and use a template XML file.

Autoit script. Compile as an exe and run this as a Windows task. It will work out the latest version by reading [1]. It will save the msi into the directory $wpkg_path\[version number]\. The WPKG template is in the dir $wpkg_tree_file - copy of the template below the Autoit code. The template file is copied locally and the string 'VERSION_NUMBER' replaced with the real Google Driver version number. The edited template file is then copied into the live WPKG tree, in my case $wpkg_tree_file.

;Script to look for the current version of Google Drive, look to see if we've already downloaded it onto the WPKG programs dir.  If we haven't, download it and then create an updated WPKG XML file.
