Error While loading project in VS2012

Error 109 'Could not load file or assembly 'DevExpress.Web.v14.1, Version=14.1.7.0, Culture=neutral, PublicKeyToken=b88d1754d700e49a' or one of its dependencies. Invalid pointer (Exception from HRESULT: 0x80004003 (E_POINTER))'

I use to work on VS2008 previously, but recently I have moved from VS2008 to VS2012. Everything is working good, but whenever I add Devexpress Control(Grid View) in my project, I am getting this error message.

I have searched for this error on Google, and everytime I have found the below mentioned link but it didn't solved my problem.

Link I use to get from Google : https://www.devexpress.com/Support/Center/Question/Details/KA18620

Please help.

I think that your project is targeted to a .NET version prior to 4. Version 14.1 of DevExpress components requires .NET 4+. Change your .NET version in the project properties.
