I had two versions of SQLEXPRESS on my computer earlier ,now I have uninstalled 2012 SQLEXPRESS from my computer
Now when I try to attach .MDF file made in 2012 version it gives me error.

Is there any way to do that without installing back the 2012 version ..Currently I'm running on 2008 version.

Thanks in advance.

I may be no expert on the Microsoft sql server but a few things do appear obvious. One is that if you want the version 2008 to read the file then you will need to convert the file to a 2008 file aka the 655 or earlier datatype indicated in the error message. To do so I would emajine you would get both database engines accisible from the same system and retrieve records from one database while inserting into the older version. Note that this will most likely require a script weather it's php or some other language to process the results. But if it's possible to just upgrade the problem program it would probably be easier to do so.

So if I have to attach the file I have to re install 2012 version and then I can.
