If you are running a non-en-US Windows 10, and wish to install Remote Server Administration Tools for Windows 10, you may notice the install does not succeed.
The installation of RSAT finishes after about 5-10 seconds, claiming it has been installed successfully. However, the RSAT tools are nowhere to be found, and update history does not show KB2693643 to be installed.
Attempting to install RSAT through Dism.exe fails with error : 0x800f081e
Dism.exe /Online /Add-Package /PackagePath:WindowsTH-KB2693643-x64.cab Deployment Image Servicing and Management tool Version: 10.0.10240.16384 Image Version: 10.0.10240.16384 Processing 1 of 1 - Adding package Microsoft-Windows-RemoteServerAdministrationTools-Client-Package-TopLevel~31bf3856ad364e35~amd64~~10.0.1 0514.4 Error: 0x800f081e The specified package is not applicable to this image. The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log
Looking at the log mentioned in the above output, we see:
At the moment, RSAT only installs if the English (US) language pack is present.
To resolve the issue, install the English (US) language pack in Windows 10, then install the RSAT package. Setting English as the default display language is not required.
