Before deploying SMS in a multilingual site hierarchy, you should consider the following installation issues:
Local-language versions of SMS server and client software are only supported on the matching local-language version of the operating system. For example, the French-language version of the SMS server software is not supported on a German-language operating system. The German, French, Japanese, Korean, and Traditional and Simplified Chinese versions of SMS clients and servers are only to be installed on their respective language operating systems. The only exception is the English version of the SMS server software, which is supported on all language operating systems.
