dll reference conflict between C:\Windows\Assembly folder and Temporary ASP.NET folder

dll reference conflict between C:\Windows\Assembly folder and Temporary
ASP.NET folder

I am using DevExpress v10.2 in my application. After deploying my
application in IIS of my production machine, i am getting an issue as 'The
type DevExpress.Web.ASPxEditors.ASPxLabel' exists in two locations. One of
the location is C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary
ASP.NET Files contains DevExpress v12.2 dll and the other location is
C:\Windows\assembly contains DevExpress v10.2 dll which is not letting the
application to run. I have stopped the IIS and cleared the folders in
"Temporary ASP.NET Files" folder and again tried running it, but resulted
in the same issue. I have given the screenshot of my issue.
Please advise on solving this issue.
Thanks in advance.
