When you get this error like I did, and it tells you the assembly file version or error says The located assembly's manifest definition does not match the assembly reference.
you'll have to follow the steps to get the dll files from windows assembly GAC
my example is about the ReportViewer.ProcessingObjectModel version so I'll use this. However you can use whatever is missing dll in your error
Open a command prompt in Administrator mode
Type cd \windows\assembly\gac_msil\Microsoft.ReportViewer.ProcessingObjectModel press Enter
Type dir so it lists the files/folders inside and press Enter and check your required version folder is available
in my case my required version was 11.0.0.0__89845dcd8080cc91 so I typed cd 11.0.0.0__89845dcd8080cc91 and press Enter
you'll be able to find Microsoft.ReportViewer.ProcessingObjectModel.dll in this folder
now we will copy this dll type command copy*.dll c:\dll (or any folder you wish to copy) and press Enter
now the dll is copied to your specified folder and you can use it as a reference in your project folder.
