About the SQL Server License Terms
The Microsoft Software License Terms are copied to the local computer when SQL Server is installed. When multiple instances of the same edition and language of SQL Server are installed on the same computer, a single copy of the license terms will apply to all instances of that edition and language. The files are written to: %ProgramFiles%\Microsoft SQL Server\100\License Terms\ or %ProgramFiles(x86)%\Microsoft SQL Server\100\License Terms\.
When multiple instances of the same SQL Server edition and language are installed on the same computer, a single copy of the license terms will apply to all instances of that edition and language.
