The error message "A partially deleted previous installation was detected"

If a standard uninstall didn't work, you must manually delete the "ghost" directories that the installer is seeing.

Run the installer with this specific command: GoogleDriveSetup.exe --skip_version_check Restart your computer once the installation completes.

Download and run the Google Drive Cleanup Tool (search Google Help for the latest link). It removes all traces of Drive.
