MS SSMS - Object reference not set to an instance of an object. (Microsoft.VisualStudio.Editor.Implementation)

Question

I am facing an issue in MS- Sql Server Management studio 2014. Upon writing a query and executing it in SSMS, i get the following error. Object reference not set to an instance of an object. (Microsoft.VisualStudio.Editor.Implementation)

I have uninstalled and installed SSMS and Visual Studio several times to make it work but have not been successful. Have also gone through google and a lot of forums but no luck yet. I had VS 2015 installed which i have uninstalled and yet getting the error in SSMS.

Here is the additional info:

• Microsoft SQL Server Management Studio 12.0.2000.8
• Microsoft Analysis Services Client Tools 12.0.2000.8
• Microsoft Data Access Components (MDAC) 6.1.7601.17514
• Microsoft MSXML 3.0 4.0 6.0
• Microsoft Internet Explorer 9.11.9600.18893
• Microsoft .NET Framework 4.0.30319.42000
• Operating System 6.1.7601

Answer 1

I have been able to get this fixed. This issue was due to a security patch with a defect. I uninstalled the security patch**(KB 4055002)** from .Net framework and it started working fine.
