2018-06-28 10:40:26.220 Caught HRESULT:
Cause
Local "Users" group contains pseudo-groups,  "NT AUTHORITY\INTERACTIVE" and "NT AUTHORITY\Authenticated Users" which are not real groups in the sense that they could be queried for membership.
 
Resolution
The issue is fixed in RSA Agent for Windows 7.3.3.126.
Call RSA Technical Support to obtain this hotfix.
Workaround
Set challenge as "All users except", instead of "Users in"

Challenge: All users except
Group: .\Administrators
