Installer encountered an error: 0x8007177f

CAUSE
This problem occurs because you cannot encrypt files by using Encrypting File System (EFS). You cannot encrypt files by using EFS because a Group Policy setting is applied to the computer. The Group Policy setting prevents the computer in the domain from encrypting files by using EFS.
