There is another possibility also. If at the site that holds the backup files you have one device that has endpoint installed on it, you can use that to recover files from other devices backups also.
In the FLR wizard, you need to go to the page "Backup Location" and then select the correct location. It might be that the FLR wizard will be on the second page (Restore Point) automatically, so you need to use the Back button to go to that first page. Select the correct backup and you can restore whatever you want
