Just download the setup executable, install it elsewhere like the home computer and then copy the two files from the c:programsgoogledrive folder.
To download the installer, visit http://drive.google.com and look on the left-bottom corner for the download links.
Administrative permissions are only required to install the program on the programs folder, other than that it works ok without any other issues.
The good thing is being able to synchronize a folder on your disk just like dropbox with a good interface to edit the files from the internet or from the android phone.
Hope this tip helps others out there, take care!
