Problem:

While running the psconfig wizard I got following error message. SQL Server at SharePoint 2013 has an unsupported version 10.50.1600.1. Please refer to …..

Cause:

The SQL version 10.50.1600.1 is SQL server 2008 R2 RTM version.

Solution:

The SQL version should be on Service Pack 1 to successfully run the configuration wizard for SharePoint 2013

You can download the SQL R2 Service pack from here http://www.microsoft.com/en-us/download/details.aspx?id=26727

Once the Service Pack for SQL is installed, please run the SharePoint 2013 psconfig wizard again and this time it should run successfully
