Reverting an unsuccessful installation with SGNRollback

Note SGNRollback should only be used with Windows 7 without BitLocker.

If there is an unsuccessful attempt to install SafeGuard Enterprise on an endpoint, the computer may be unable to boot and may be inaccessible for remote administration.

SGNRollback can repair an unsuccessful SafeGuard Enterprise installation on an endpoint, if the following applies:

  • The Power-on Authentication freezes during the first startup and the computer can no longer boot.

  • The hard drive is not encrypted.

SGNRollback automatically reverts the effects of an unsuccessful installation of SafeGuard Enterprise by

  • Enabling the blocked computer to boot,

  • Removing SafeGuard Enterprise and

  • Undoing any modifications to other operating system components.

Start SGNRollback from a Windows-based recovery system, either WindowsPE or BartPE.
