All SMS client workstations that are enabled with CAC authentication source
                  				require ActivClient software, a Windows compatible smart card reader, and the
                  common
                  				access card (CAC). ActivClient must already be installed and configured before
                  you
                  				can configure CAC authentication on the SMS. ActivClient is supported on the
                  				following Windows operating systems. 
                  
| Windows operating system | ActivClient version | 
| Windows 7 (32- and 64-bit) | ActivClient 6.2 or ActivClient 7.0.2 | 
| Windows 8 (32- and 64-bit) | ActivClient 6.2 or ActivClient 7.0.2 | 
| Windows 10 (32- and 64-bit) | ActivClient 6.2 or ActivClient 7.0.2 | 
| Windows 11 (32- and 64-bit) | ActivClient 7.4 (recommended) |
