5. Do the same for %Temp%, i.e. click %Temp% to highlight it and change Folder Isolation to Full access
6. If Google Drive folder is in its default location, do the same for %Profile%. If you chose a different location for Google Drive folder, give the folder directly above it Full access; you may have to Add empty folder to package if it is not already present in the package, e.g. if you assigned Google Drive folder to Documents, you would Add empty folder and name it %Personal% and give %Personal% Full access.
7. Save package
Google Drive package should now work and download files to the host system, i.e. not the package's sandbox.
