SQL Server 2008数据库的版本为655. SQL Server 2008 R2数据库为661.您尝试将2008 R2数据库附加到2008实例，但不支持此操作。
您需要将SQL实例升级到至少2008R2才能打开文件（但请注意，如果您随后将现有数据库附加到新实例，则您赢了然后能够再次在SQL 2008中打开。）

You may have installed VS 2012, but you are using a SQL 2008 instance: Visual studio does not install SQL for you.
SQL Server 2008 databases are version 655. SQL Server 2008 R2 databases are 661. You are trying to attach an 2008 R2 database to an 2008 instance and this is not supported.
You need to upgrade your SQL instance to at least 2008R2 to open the file (but be aware that if you subsequently attach your existing DBs to the new instance, you won't be able to open then in SQL 2008 again either).
