I have an issue with my Dell Inspiron 3520 .By mistake I have uninstalled the Backup and Recovery software I have downloaded Backup and Recovery app files Backup-and-Recovery_Application_64M9D_WN32_1.8.1.71_A00.EXE. But while installing, I am getting an error message that it can be installed on Dell systems only. I also tried the older version Dell_Backup_and_Recovery_1.7.5.64.exe. But getting the same error. Pl advise.
