  • Hi denkyira,

    SQL server 2008 R2 is out of Extended support at 7/9/2019. Please refer to End of support for SQL Server 2008 and SQL Server 2008 R2. I suggest you upgrade your SQL server to a newer version.

    For your issue, please check if below link could help you.

  • Hi 

    Thanks a lot for your response. I have reviewed the Microsoft.sqlserver.smo in my C:\Windows\assembly and compared it with the one in C:\Program Files\Microsoft SQL Server\110\SDK\Assemblies and could tell there is a difference.


    10.50.1447.4----->C:\Program Files\Microsoft SQL Server\110\SDK\Assemblies

    I am going to follow the link you gave to fix my issue since I have a good working image.

    I will update when l am done tonight
