When installing the Remote Server Administration Tools for Windows 7 (RSAT), you may receive the following error message:
"This update is not applicable to your computer"
This error will occur if you attempt to install RSAT after installing Service Pack 1 for Windows 7. The RSAT tools are designed for the RTM version of Windows 7 and are not compatible with Service Pack 1. However, Service Pack 1 includes updated components for RSAT, so if RSAT is installed before Service Pack 1, the issue will not occur and the components will be updated automatically.
Install RSAT tools before installing Service Pack 1 for Windows 7. If Service Pack 1 for Windows 7 is already installed, it can be uninstalled and then reinstalled after the RSAT tools are installed.
Microsoft has confirmed this to be by design, as RSAT was designed for Windows 7 RTM version. A newer version of RSAT is slated to be released in the future. More information on the RSAT tools is available at the following web site:
